Abstract EN
A novel variable structure compensation PID control, VSCPID in short, is proposed for trajectory tracking of asymmetrical hydraulic cylinder systems.
This new control method improves the system robustness by adding a variable structure compensation term to the conventional PID control.
The variable structure term is designed according to sliding mode control method and therefore could compensate the disturbance and uncertainty.
Meanwhile, the proposed control method avoids the requirements for exact knowledge of the systems associated with equivalent control value in SMC that means the controller is simple and easy to design.
The stability analysis of this approach is conducted with Lyapunov function, and the global stability condition applied to choose control parameters is provided.
Simulation results show the VSCPID control can achieve good tracking performances and high robustness compared with the other control methods under the uncertainties and varying load conditions.
