Abstract:
?An adaptive complementary sliding mode control is proposed to solve the problem that the servo system of permanent magnet linear synchronous motor( PMLSM) is vulnerable to be affected by the nonlinear factors. The nonlinear factors of PMLSM include the variations of system parameter,the inherent and effect of motor,and the disturbance of the external uncertainty. Complementary sliding mode control combined the integral sliding surface and generalized error sliding surface,and the system state trajectory was defined in the intersection of two faces. Therefore,it shortened the time of the state trajectory to reach the sliding mode surface,and improved the position tracking accuracy. In order to further improve the robust tracking performance of the system,adaptive control was proposed to estimate the upper bound of uncertain disturbance factors. It can reduce the influence of the uncertain factors on the system,and improve the chattering phenomenon of sliding mode control. The experimental results show that the proposed control method is feasible and effective,and adaptive complementary sliding mode control not only improves the tracking performance of the system,but also effectively reduces the effects of uncertainty on the control system.
