摘要
The nonlinear friction characteristics in line cylinder pneumatic servo control system are analyzed. The friction can be seen as the disturbance in the global sliding mode variable structure control (SMVSC). The system is robust during the whole response process, by changing controller structure or adjusting control parameters to suppress the disturbance. Numerical simulation shows that the SMVSC scheme has better dynamic and static performance and robustness than that of the PD scheme. Finally, the feasibility of the SMVSC is validated through experiments on the ball & plate XY trajectory pneumatic control system, and it has precise tracking performance.
