The Disturbance Observer concept has 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. A number of applications of the disturbance observer technique will be discussed. Particularly, it shows that the disturbance observer could be used for fault detection and diagnosis by directly treat faults as disturbances. It is argued that comparing with the widely used innovation or residual based fault detection and diagnosis methods, the disturbance observer technique offers a number of promising features.
