Optimal Control with Zero Steady-state Errorfor Linear Systems with Sinusoidal Disturbances
This paper considers the design of op- timal control law with zero steady-state error for lin- ear systems affected by external sinusoidal disturbances with known frequencies but unknown amplitudes and phases. Based on the internal model principle, a distur- bance compensator is constructed such that the system model with external disturbances is transformed into an augmented open-loop system without disturbances. Solving the problem of disturbance rejection with zero steady-state error becomes solving the problem of the design of an optimal controller for the augmented plant. By the optimal control theory, we obtain a dynamic op- timal feedback control law with zero steady-state error. The obtained optimal control law is physically realiz- able. Simulation results demonstrate the validity of the proposed approach.
