Based on the internal model principle, a disturbance compensator is constructed to cancel the disturbances completely. The optimal disturbance rejection problem with zero steady-state error for time-delay systems affected by disturbances is transformed to an optimal control problem without disturbances. Then, using the sensitivity approach, the optimal control law is obtained consisting of an analytic state feedback term and a compensation term which is a series sum of the ad joint vectors. By intercepting finite sum of the adjoint vectors series, a suboptimal feedback control law with zero steady-state error is obtained.
