| Abstract: | The optimal control problem is considered for linear discrete time-delay systems affected by external persistent disturbances.By using successive approximation approach,the feedforward and feedback optimal control law is presented,and a disturbance observer is designed to make the optimal controller physically realizable.Simulation examples demonstrate that the control law is efficient and more robust than the classic state feedback optimal control law with respect to errors produced by the external disturbances. |
