Recent advances on intelligent control for mechatronic systems

Prof. Shihua Li

Southeast University, China

Abstract

For mechatronic systems, nonlinearities (frictions, backlash, saturation, etc.), complex internal dynamics, time-varying parameters, external disturbances and complex work tasks make control design a very challenging work. In this talk we will discuss on various advanced modeling, analysis and intelligent control techniques for mechatronic control systems. Compared with high gain control and integral control methods, the disturbance estimation based control method provides a different way to handle disturbance. Disturbance estimation based robust control method can effectively improve the disturbance rejection ability and ensure the robustness of closed-loop system. There are also development requirements for intelligent functions of mechatronic systems, such as parameter self-adjustment and adaptation, sensorless control, vibration suppression, etc. Some new research developments and results on this topic will be introduced. Considering the characteristics of mechatronic control system, several kinds of composite control design schemes based on disturbance estimation and compensation are presented with experimental or application verification results.

The Stability Analysis of Recurrent Neural Networks With Multiple Equilibria

Prof. Zhigang Zeng

Huazhong University of Science and Technology, China

Abstract

The coexistence of multiple equilibria is a ubiquitous phenomenon in most dynamic systems such as physical systems, biological systems, and engineering systems, etc. In particular, in some applications of recurrent neural networks (RNNs), there are the needs for the coexistence of multiple stable equilibria. The stability analysis of RNNs with multiple equilibria is thus deemed to be of great importance from both theoretical and practical standpoints. In this talk, I provide an overview of the complete stability and multistability analysis of RNNs with multiple equilibria. The hierarchies of various RNN modes and activation functions as key factors affecting the number of equilibria are provided. Then a taxonomy with representative references on complete stability analysis of RNNs is summerized. Further, the main analytical steps for multistability are discussed and works on the multistability analysis of various classes of RNNs are reviewed. Finally, some challenging yet interesting issues for further research endeavors are prospected.
