Abstract

This paper examines the mechanism of disturbance rejection in control systems employing a technique called equivalent-input-disturbance estimation. Analysis of the mechanism shows that the filter in the control system strongly affects the disturbance rejection performance. A new method of designing such control systems that employs H_infin control theory and linear matrix inequalities is presented; and simulations of a magnetic levitation system demonstrate its validity
