一、主讲题目：Lectures on Modeling and control of Hysteresis Nonlinearities in Smart Actuators
讲座一：Modeling of Hysteresis Nonlinearities in Smart Actuators
时间：2021年5月31日14:00-14:45
报告摘要：
Smart material based actuators are playing an increasingly important role in micro/nano-positioning applications. However, such actuators with different input frequencies and mechanical loads exhibit complex dynamics and hysteretic behaviors, posing a great challenge on applications. The characterizations of their dymanics have emerged as a significant problem. This talk is intended to raise awareness of modeling techniques and to provide an opportunity to discuss state-of-the-art solutions for the problems. The talk is designed to appeal to an audience from different backgrounds. People working in the area of control will have a chance to interchange ideas and to view problems from different perspectives. People working in other areas will also benefit by understanding the new methods and technologies developed for control’s point of view.
讲座二：Control of Hysteresis Nonlinearities in Smart Actuators
时间：2021年5月31日15:00-15:45
报告摘要：
For decades, the existence of hysteresis nonlinearities in smart materials has provided one of the most difficult challenges to control design engineers since the entire Laplace domain and most state space control design techniques were developed exclusively for differentiable linear or nonlinear systems. Hence, the controllers were designed where the existence of hysteresis nonlinearities in practical systems were neglected. When the systems are considered with hysteresis (non-differentiable) nonlinearities, these methods encountered substantial difficulties in the analysis, model fitting and control design stages. It was extremely difficult, if not impossible, to design or prove stability of such systems. This talk is intended to discuss state-of-the-art control techniques, especially in the absence of complete information concerning the system model and state.
