摘要

The paper studies sliding mode variable structure control system for a novel gearless windlass balance oil pumping unit(GWBOPU) driven by low-speed and high-torque permanent magnet synchronous motor (PMSM). By analyzing the correlative relationships of the motor and the load, a mathematics model for GWBOPU is established. Base on this model, a speed sliding mode controller is designed by regarding the load speed as the control object. To guarantee the higher operating performance of the system, the running speed is also planned and designed according to different operating conditions. The simulation and experiment results show the control system has satisfied dynamic performance and strong robustness to disturbances.
