摘      要：This paper studies the optimal control with zero steady-state error problem for nonlinear large-scale systems affected by external persistent *** nonlinear large-scale system is transformed into N nonlinear subsystems with interconnect *** on the internal model principle,a disturbance compensator is constructed such that the ith subsystem with external persistent disturbances is transformed into an augmented subsystem without *** to the sensitivity approach,the optimal tracking control law for the ith nonlinear subsystem can be *** optimal tracking control law for the nonlinear large-scale systems can be obtained.A numerical simulation shows that the method is effective.
