Abstract
In practical control systems, it is inevitable to have plant uncertainties and external disturbances, which are major sources to make the robust control problem challenging. Not surprisingly, many researchers have developed various techniques to efficiently cope with the disturbance and plant uncertainties. One of these ideas is to construct an observer or estimator, called disturbance observer, which estimates the disturbance and the effect of uncertainties, and then use this estimate to achieve the control goal. In this talk, several disturbance observers are introduced with simple examples to capture the key idea. The disturbance observers to be covered are as follows. 1) The disturbance observers by Johnson and Chen: design an observer as if the disturbance is known and realize it without using the disturbance. 2) The disturbance observer by Ohnishi and its extensions which use inverse of nominal model. 3) The extended state observer based disturbance observer by Han and similar approaches. 4) Disturbance observers based on sliding mode or variable structure.
