Abstract:

Disturbance rejection and robustness are essential in all the control systems designs. 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 analysis of their similarities and differences with a number of well-known control methods such as robust control and adaptive control. It shows that DOBC and related methods provide a promising, flexible and versatile approach in dealing with disturbance and uncertainty. Finally challenges in further development of DOBC techniques will be discussed.
