Title of Speech: CPS driven optimal control system for energy-intensive equipment
Abstract: 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.

Title of Speech: Neuro-inspired Adaptive SoCs and Applications
Abstract: The biological brain implements parallel computations using a complex structure that is different from the conventional von Neumann or load/store computing style. Our brain is a low-power, fault-tolerant, and high-performance machine! Hardware implementations of artificial neural (AI) networks are efficient and effective methods to provide cognitive functions on a chip. This talk first presents an overview of the low-level neuron modelling, on-chip learning and the upper level AI models applications. The second part of the talk focuses on DNN (deep neural network) hardware implementation with specialized adaptive hardware components and on-line learning capability on a manycore adaptive system-on-chip (SoC). A case study on low-power and high-performance Neuro-inpired SoC implementiaon based on convolution neural network and adaptive learning is given. The adaptive neuro-inpisred SoC is targeted for a new class of applications ranging from autonomous IoT devices, intelligenet robots, and deep learning to high-performance computing co-/processing.

Title of Speech: Neural Network Based Iterative Learning Control for Nonlinear Systems
Abstract: In this talk, an iterative learning control (ILC) algorithm for nonlinear systems by using neural network design is presented. Iterative learning control is one of the most effective control strategies for systems which are asked to repeat the control tasks over and over again during a finite interval. In this study, we aim to propose a neural network based iterative learning controller so that only input/output data are required for the controller design. A new approach using two neural networks is employed. The first neural network called neural controller (NC) is used as the main iterative learning controller for the closed loop stability. An adaptive law is developed to update the neural weights during the control iterations in order to guarantee the error convergence. As the information of system sensitivity function is required to design the adaptive law, a second neural network called neural identifier (NI) is used as an estimator to provide an estimated sensitivity function. The weights of neural identifier will be tuned after the current trial and a good estimated sensitivity function can be provided for next iteration. The adaptive laws for the weights of both neural controller and neural identifier as well as the analysis of closed loop learning performance are determined via a Lyapunov like analysis. A comparison between this new design and traditional PID-type iterative learning control will also be discussed. Finally, some numerical simulations and experimental results are shown to demonstrate the effectiveness of the proposed scheme.
