报告内容简介:
Disturbance Observer Based Control (DOBC) and related methods have been researched and applied in various industrial sectors in the last four decades. This talk gives an overview of a number of widely used linear and nonlinear disturbance/uncertainty estimation techniques, and then discusses and compares various compensation techniques and the procedures of integrating disturbance/uncertainty compensation with a (pre-designed) linear/nonlinear controller. It provides in-depth analysis of the relationships between these methods and, more importantly, on their similarities and differences with a number of well-known control methods. It shows that DOBC and related methods provide a promising, flexible and versatile approach in dealing with disturbance and uncertainty, which is complementary to robust control and adaptive control methodologies. Various application examples including motion control systems will be mentioned.
