This paper describes simple adaptive control for plants with bounded nonlinear disturbances. The proposed controller is applicable to all plants whose relative degree is less than four, in which the upper bound of the high-frequency gain and the function type of disturbances must be known. Results of experiments demonstrate the controller’s effectiveness.
