摘要：
A new smooth switching control method is proposed for the four-tank coupled liquid level system, which solves the problems of serious chattering in sliding mode and slow transient response in backstepping control. Firstly, based on the four-tank system, the non-singular terminal sliding mode controller and backstepping controller are designed respectively. Secondly, the smooth switching function is designed and the two controllers are combined to realize the smooth switching control strategy. Finally, Matlab/Simulink is used to verify the designed smooth switching control strategy. The simulation results show that the smooth switching control strategy effectively combines the advantages of the non-singular terminal sliding mode control method and the backstepping control method, which have the advantages of fast dynamic response and stable and accurate steady-state response. Therefore, the control method has good control performance and practical application prospect.
