Abstract

A method of achieving integral action with regard to disturbances and unknown constant parameters is presented. The method is similar to Johnson´s (1974) “disturbance accommodating control” but is structured so that the disturbance correction or parameter estimation function can be designed without affecting the disturbance-free control. Simulation examples illustrate the method for a one-degree of freedom servo with a randomly-varying load disturbance, and for a two-degree of freedom servo with two sources of friction
