Examples of underactuated mechanical systems are almost everywhere, ranging from satellites, mobile robots to surface ships and underwater vehicles. These systems are strongly nonlinear and share a common feature that there are less number of actuators than the degree of freedom. It is well-known that there is no linear or nonlinear time-invariant continuous feedback law which can stabilize such a system with nonholonomic constraints to any given set-point. Fundamentally nonlinear approaches have been discovered and proposed by many researchers over the last 20 years.In this talk, I will first give a short review of the current state-of-the-art of controlling underactuated mechanical systems and discuss some research opportunities and challenges. Then, I will present some of our recent work on the stabilization and tracking of mobile robots and ships. Some unsolved problems will be discussed for the benefits of younger students who want to study in this exciting field.欢迎广大师生参加! 学院办公室-光电信息与计算机工程学院 9:13:14 2009-8-31 星期一
