报告题目:Analysis and Improvement of Equivalent Input Disturbance Approach

报告人: 杜友武

报告摘要：

Industrial systems usually contain disturbances that degrade control performance. Thus, disturbance rejection is one of the most important objectives in control-system design. The equivalent-input-disturbance (EID) approach, which has two degrees of freedom, has been devised and used in control engineering practice. Since one degree of freedom is directly used for disturbance rejecting, the method has the potential to achieve high disturbance-rejection performance. It uses a state observer and an EID estimator to actively estimate and compensate for the effect of disturbances on system output. It does not require the inverse dynamics of a plant, a model of exogenous disturbances, or the differentiation of measured outputs. Thus, it is simple to implement and is effective in rejecting various kinds of disturbances.

In this talk, I am going to explain the method from the basic idea to the recently developed theoretical results. First, the definition of an EID is explained. Next, the configuration of an EID estimator-based control system is described. Then, the Improvement and analysis of the EID approach are discussed in detail. Finally, some concluding remarks and future related work will be presented.

报告题目:Application research of finite-time stability theory in disturbance rejection control

报告人: 陆群

报告摘要：

For control systems, the ability to reject disturbances is crucial as it ensures stability, improves performance, enhances robustness, ensures accuracy, and increases system reliability. Effective disturbance rejection strategies enable control systems to operate more effectively and reliably, even in the presence of external disturbances or uncertainties. Finite-time stability theory provides a valuable framework for analyzing and designing control systems with stability and convergence guarantees over finite time intervals. By considering the system's behavior within a specific time frame, it enables the development of control strategies that achieve desired performance objectives in time-critical applications.

This talk will begin by exploring the theoretical foundation of finite-time stability theory. It will then discuss how finite-time stability theory can be utilized to reject system disturbances. Finally, it will outline some potential research areas for future investigation in the field of finite-time disturbance rejection.
