报告题目：Coordination and Control of Multi-Robot Systems

报告时间：2021年11月09日（周二）09:15a.m.~10:30a.m. (Beijing Time)

报告专家：胡国强 教授   新加坡南洋理工大学

报告摘要：Multi-robot systems have been advancing apace with the help of high-performance hardware and computational technologies. Despite the high-performance computing, communication, sensing, and power devices used in these systems, their effectiveness in uncertain environments appears to still fall behind the natural systems such as a swarm of ants, a flock of birds, or a team of wolves. One of the challenges in multi-robot coordination is the lack of effective distributed algorithms and designs that enable the robots to work cooperatively and safely in uncertain environments. This talk will first give a brief review of multi-robot systems, and then present some recent research results on distributed algorithms and control methods for multi-robot coordination. The research on this topic has a wide range of potential engineering applications, including surveillance and search, warehouse logistics, advanced manufacturing, and environment monitoring.

报告题目：Modeling and Control of Hysteresis Nonlinearities in Smart Actuators

报告时间：2021年11月09日（周二）10:30a.m.~11:45a.m. (Beijing Time)

报告专家：苏春翌 教授  加拿大康考迪亚大学

报告摘要：Smart actuators featuring high energy densities, large strokes and fast responses are playing an increasingly important role in micro/nano-positioning applications. However, hysteresis nonlinearities are very common in smart material-based actuators. For decades, the existence of such nonlinearities 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 actuators are considered with hysteresis 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. The development of techniques for the identification of such nonlinearities in smart material-based actuators has emerged as a significant problem in itself. This talk is intended to discuss state-of-the-art solutions for modeling and control techniques of hysteresis effects in smart actuators. The presentation and discussion will range from modeling of hysteresis, to the design of corresponding control schemes, especially in the absence of complete information concerning the system model and state.
