Abstract

In this paper, disturbance observer based quasi full information feedback control law of linear systems is proposed, where the feedback control law is with direct measurement of the plant states and the estimation of the disturbances. It shows that the system under control is input to state stable from the derivative of the disturbances to the system states provided that the given matching condition is satisfied. Furthermore, the effect of the disturbances can be compensated entirely if the disturbance is constant. The proposed scheme is verified by a simple numerical example and the stability control of four-wheel steering vehicle.
