摘      要：The optimal control design for singularly perturbed time-delay systems affected by external distur-bances is *** on the decomposition theory of singular perturbation,the system is decom-posed into a fast subsystem without time-delay and a slow time-delay subsystem with *** disturbances rejection control law of the slow subsystem is obtained by using the successive ap-proximation approach(SAA)and feedforward compensation ***,the feedforward and feed-back composite control(FFCC)law for the original problem is *** FFCC law consists of lin-ear analytic terms and a time-delay compensation term which is the limit of the solution sequence of theadjoint vector equations.A disturbance observer is introduced to make the FFCC law physically *** examples show that the proposed algorithm is effective.
