摘要：
In this paper, the performance output tracking problem of cascade system about wave equation subject to unmatched disturbance on the boundary and ordinary differential equation is considered. The wave equation with unmatched disturbance on the boundary can be used as the actuator dynamics of ordinary differential equation control system. By using trajectory planning method to transform the non-collocated disturbance to the control channel, the difficulty caused by the non-collocated disturbance is overcome. Different from the existing backstepping method, this paper presents a new state feedback controller by using the dynamic compensation method, which makes the design of the controller and the controller itself are much simpler. As a result, the uniform boundedness of the solution of the closed-loop system and the exponential tracking of the performance output are proved. The numerical simulation shows that the proposed method is very effective. © 2023 South China University of Technology. All rights reserved.
