Title: CPS Driven Control System


China has abundance of mineral resources such as magnesite, hematite and bauxite, which constitute a key component of its economy. The relatively low grade, the widely varying and complex compositions of the raw extracts, however, pose difficulties and challenges to processing industries, such as specialized equipment with excessive energy demands. One typical example is the energy intensive furnaces together with widely uncertain features of the extracts, which forms a hybrid complex system and makes 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 control system.

This talk presents the syntheses and implementation of a CPS driven control system for energy-intensive equipment under the framework of CPS. The proposed CPS driven control system consists of four main functions: (I) setpoint control; (II) tracking control; (III) self-optimized tuning; and (IV) remote and mobile monitoring of operating conditions. The key in developing the above functions is the integrated optimal operational control method that is able to seamlessly integrate the setpoint control, tracking control and self-optimized tuning together. This talk introduces the integrated optimal operational control methods we proposed recently.

Hardware and software platform of CPS driven 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 Distributed Control System (DCS) (PLS), for optimization 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 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, self-optimized tuning and remote and mobile monitoring for operating condition in the framework of CPS.

The industrial application of the proposed CPS driven 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 control system is outlined.

Title: On Data-Selective Learning


The current trend of acquiring data pervasively calls for some data-selection strategy, particularly in the case a subset of the data does not bring enough innovation. As a byproduct, in addition to reducing power consumption and some computation, the discarding of data results in more accurate parameter estimation. In many practical situations, it is possible to verify if the acquired set of data qualifies to improve the related statistical inference or if it consists of an outlier or a non-innovative entry.

In this presentation, we discuss some extensions of the existing adaptive filtering algorithms, and if time allows machine learning algorithms, enabling data selection which also address the censorship of outliers measured through unexpected high estimation errors. The resulting algorithms allow the prescription of how often the acquired data is expected to be incorporated in the learning process based on some a priori assumptions regarding the environment data.

A detailed derivation of how to implement the data selection in a computationally efficient way is provided along with the proper choice of the parameters inherent to the data-selective affine projection (DS-AP) algorithms. Similar discussions lead to the proposal of the data-selective least-mean square (DS-LMS) and data-selective recursive least squares (DS-RLS) algorithms. Simulation results show the effectiveness of the proposed algorithms for selecting the innovative data without sacrificing the estimation accuracy, while reducing the computational cost.

Title: Passive circuit theoretic paradigm for digital modeling of nonlinear PDEs of classical physics


In this talk, we discuss how the circuit theoretic paradigm can be extended to include multidimensional and nonlinear passive systems to model a variety of phenomena from classical physics. While mechanical, electromagnetic, acoustic, and heat diffusion problems can be treated in this way in a relatively straightforward manner, the centerpiece of the talk will be the examination of the full Navier-Stokes equation (including heat flow) within this framework. All ingredients of lumped passive circuit theory are kept intact, but multidimensionality and simple nonlinear aspects are appropriately introduced to represent the nonlinear PDEs associated with the physical phenomena in circuit theoretic terms. The details of the feasibility of such mapping for viscous fluids have not been explicitly discussed in the open literature, which will be focus of this talk. If time permits, related magneto-hydrodynamic and relativistic fluid dynamic equations will also be undertaken in this context. Since such continuous domain multidimensional circuits are known to be internally passive, robust digital equivalents via identification with wave digital principles are feasible, and the methodology opens up a new strategy for numerical modelling and solution of a large class of partial differential equations of physical origin.
