CPS driven optimal control system for energy-intensive equipment
Prof. Tianyou Chai, Northeastern University, China.
China has abundance of mineral resources such as magnesite, hematite and bauxite, which constitute a key component of its economy. The relatively low grade, and the widely varying and complex compositions of the raw extracts, however, pose difficult processing challenges including specialized equipment with excessive energy demands. The energy intensive furnaces together with widely uncertain features of the extracts form hybrid complexities of the system, where the existing modeling, optimization and control methods have met only limited success. Currently, the mineral processing plants generally employ manual control and are known to impose greater demands on the energy, while yielding unreasonable waste and poor operational efficiency. The recently developed Cyber-Physical System (CPS) provides a new key for us to address these challenges. The idea is to make the control system of energy intensive equipment into a CPS, which will lead to a CPS driven optimal control system.
This talk presents the syntheses and implementation of a CPS driven optimal control system for energy-intensive equipment under the framework of CPS. The proposed CPS driven optimal control system consists of three main functions: (i) setpoint control; (ii) tracking control; and (iii) self-optimized tuning. The key in realizing the above functions is the integrated optimal operational control methods to implement setpoint control, tracking control and self-optimized tuning together seamlessly. This talk introduces the integrated optimal operational control methods we proposed.
Hardware and software platform of CPS driven optimal control system for energy-intensive equipment is then briefly introduced, which adopts embedded control system, wireless network and industrial cloud. It not only realizes the functions of computer control system using DCS (PLS), optimization computer and computer for abnormal condition identification and self-optimized tuning, but also achieves the functions of mobile and remote monitoring for industrial process.
Then, using fused magnesium furnace as an example, a hybrid simulation system for CPS driven optimal control system for energy-intensive equipment developed by our team is introduced. The results of simulation experiments show the effectiveness of the proposed method that integrates the setpoint control, tracking control and self-optimized tuning in the framework of CPS.
The industrial application of the proposed CPS driven optimal control system is also discussed. It has been successfully applied to the largest magnesia production enterprise in China, resulting in great returns. Finally, future research on the CPS driven optimal control system is outlined.

From smart grids to cyber energy society system
Prof. Yusheng Xue, Honorary President of State Grid Electric Power Research Institute, China.

Smart Grids (SGs) as cyber-physical systems in power (CPSP) in nature are electric networks that use innovative and intelligent monitoring, control, communication, and self-healing technologies to deliver better connections and operations for generators and distributors, flexible choices for prosumers, and reliability and security of electricity supply. However, in line with the global movement towards a sustainable renewable energy future to address Climate Change, SGs cannot fully reflect the requirements of dominating renewable energy generation, stringent economic and environmental constraints, market competition, social and regulatory requirements. On one hand, electric energy plays a central role in the whole energy supply chain since changing the energy from electric form to non-electric one may not be as effective as using electricity directly. On the other hand, any changes in primary energy and end-use energy significantly affect electric power reliability as well as economy. A more holistic (system-of-system) approach needs to be taken to deal with future energy, and a new concept of CPSSE (cyber-physical-social systems in energy) is proposed. Consideration should be given to coordination of environmental, economic, social factors and human behaviors, a hybrid research framework across various disciplines concerned with different time and space scales. This enables collaborative mining big data with hidden causal relationships in the complex cross social, technological, economical, and environmental dimensions. The driving force induced by interaction between them may be much more powerful than the internal driving force of information systems, energy systems, and human societies themselves.

What is medical innovation? From biomedical engineering point of view
Prof. Mitsuo Umezu, Waseda University, Japan.
The Japanese Government has a special policy to promote medical innovation for overall happiness of nations. One of the epoch-making actions is related to a revision of "The pharmaceutical affairs act". It was originally established in 1943, and fully revised in fall, 2014, suitable for advanced medical technologies. Then, the name of the act was changed to "The act to ensure a quality, efficacy and safety of medical products and equipment". Another great action was an establishment of the "Japan Agency for Medical Research and Development (AMED)" in spring, 2015. AMED engages in research and development (R&D) in the field of medicine, establishing and maintaining an environment for this R&D, providing a mixture budgets, funding from the Ministry of Education(30%), the Ministry of Health(55%), and the Ministry of Economy(15%).
Biomedical engineering faculty members at Waseda University have conducted several trials to get on a "medical innovation" policy, including a development of human resources: (1) Practical bioengineers, having a valuable experience on true collaboration between Medicine and Engineering towards clinical application, and (2) Medical regulatory science specialists (PhD), having a professional skill to propose future medical policies.

Towards cognitively-inspired Data Science based on context-aware, multi-modal Big Data Analytics: Selected real-world Case Studies
Prof. Amir Hussain, University of Stirling, UK.
Cognitive Data Science is a rapidly developing discipline, bringing together neurobiology, cognitive psychology, Big Data and artificial intelligence. Ongoing pioneering work at Stirling University is exploring the development of cognitively-inspired Data Science approaches based on context-aware, multi-modal Big Data Analytics, for solving challenging real world applications. Two case studies are introduced in this talk. Firstly, on-going research into cognitively-inspired multi-modal speech perception has led to the development of a novel context-aware, audio-visual speech processing system. The proposed framework exploits cognitively inspired use of both audio and visual (including lip-tracking) information, with potential applications in next-generation multimodal hearing aids and listening device technology. The second case study focusses on open-domain sentiment analysis of natural language text using sentic computing: a novel multi-disciplinary paradigm, exploiting the semantic, latent and implicit meaning of natural language concepts. Ongoing extensions of this work include a cognitively-inspired emotion recognition system based on contextual multimodal input, including natural language text, audio and facial information, which is shown to significantly outperform state-of-the-art systems. We present a brief summary of these exciting multi-disciplinary research areas, and outline some future research directions and challenges.

Information Granularity in Data Science and Intelligent Systems: Conceptual and Development Environment
Prof. Witold Pedrycz, The University of Alberta, Canada.
Information granules play a pivotal role in acquiring, representing, processing, and communicating knowledge at a suitable level of abstraction especially in the context of modelling and analysis of complex systems. There are challenging objectives of conceptual and algorithmic nature. Designing information granules is paramount importance to all pursuits of Granular Computing.
The talk offers a comprehensive and systematically structured overview of methodologies and algorithms of designing information granules along with a suite of representative applications in data analysis, system modelling, and decision-making. The taxonomy embraces two main categories of data-driven and knowledge-oriented approaches. We introduce and discuss a principle of justifiable granularity, which serves as a key design vehicle facilitating a formation of information granules completed on a basis of available experimental evidence. Recent advances of the principle are discussed including a collaborative version of the principle supporting data analysis carried out in the presence of distributed data, context-based version of the principle incorporating auxiliary sources of knowledge, and its hierarchical version facilitating handling experimental evidence being available at several levels of specificity (abstraction). A collection of design scenarios supporting a formation of hierarchies of information granules of higher type and higher order is presented.
In the realm of applied investigations, we discuss a number of representative constructs including collaborative mode of discovery of relationships through constructing granular bi-directional and multi-directional associative memories and stacked granular auto-encoders being regarded as building modules of deep learning architectures.

On Discontinuous Observers: From Basic Properties to a Robust Fault Detection and Condition Monitoring Tool
Prof. Sarah Spurgeon, University College London, UK.
Sliding mode observers have generated a ground swell of interest in recent years. These observers have unique properties. Their ability to force the error between the measured plant output and the output of the observer to be identically zero produces a set of state estimates that are precisely commensurate with the actual output of the plant. It is also the case that analysis of the applied observer injection signal, the so-called equivalent injection signal, contains useful information about the mismatch between the model used to define the observer and the actual plant. This lecture presents an overview of both linear and non-linear sliding mode observer paradigms. The use of the equivalent injection signal in problems relating to fault detection and condition monitoring is demonstrated. A number of applications specific results are also described.

Decarbonizing the whole energy chain from top to tail - control challenges
Prof. Kang Li, Queen's University Belfast, UK.
No single solution currently exists to achieve the utopian desire of zero fossil fuel consumption in addressing the global challenge of sustainable energy and environment. It is evident that the energy mix will contain a large variation in stochastic, intermittent and distributed sources of renewable energy such as wind and solar power. The increasing prominence of renewable and cleaner energy resources in the pursuit of legally binding UK and European energy targets spurs all stakeholders and sectors on to plan for the unique challenges such promising sources present. This presentation will discuss various control challenges towards the de-carbonization of the whole energy chain from top to tail, including emission reductions from traditional thermal plants, integration of significant renewable power, electrification of transportation, and energy efficiency in building and manufacturing industry. The significant role of intelligent control techniques in transforming the energy system to a future energy network is highlighted and demonstrated.
