APPLICATION OF ADAPTIVE VARIABLE SPEED BACK-STEPPING SLIDING MODE CONTROLLER FOR PMLSM POSITION CONTROL

In this research, an adaptive variable speed back-stepping sliding mode controller (AVSBSMC) is proposed to control the permanent magnet linear synchronous motor (PMLSM) on high-precision positioning servo system platform. This controller combines the dynamic features of variable speed control (VSC) and the positioning characteristics of adaptive back-stepping sliding mode control (ABSMC). Firstly, the detailed dynamic machine model of PMLSM is established. Secondly, the proportional-integral-derivative (PID) and ABSMC controllers are proposed to compensate the uncertainties in position control. Then, the one provides the better servo performances is the position controller in the motor system. Thirdly, the variable speed controller (VSC) and each segment of the variable speed sliding functions are designed to combine with the ABSMC controller. Switching control is then used to change the system control mode accomplishing the high-precision positioning control. Our experimental results demonstrate that the AVSBSMC enhance the positioning accuracy of linear motor and reduce the transient overshoot effectively.
