Abstract

A novel control strategy based on finite time control and super-twisting observer is proposed to improve the control performance and robustness for permanent magnet synchronous linear motor (PMSLM) drive system. First of all, the velocity-current single loop control which called non-cascade structure control is proposed by the finite time control, then the response velocity of the PMSLM drive system can be improved. Secondly, to improve the disturbance rejection performance, a super-twisting observer is designed to feedforward the load. Furthermore, the strictly convergence of the proposed control strategy is implemented. Finally, comparative simulations and experiments are designed on PI control, sliding mode control, and the proposed control method. Results demonstrate that the proposed method has better robustness and control performance.

基于超扭转观测器的PMSLM非级联有限时间控制

为了提高永磁同步直线电机(PMSLM)驱动系统的控制性能和鲁棒性，提出了一种基于有限时间控制和超扭转观测器的控制策略。首先，通过有限时间控制提出了速度-电流单环控制，即非串级结构控制，从而提高了PMSLM驱动系统的响应速度。其次，为了提高系统抗扰性能，设计了超扭观测器对负载进行前馈。此外，还实现了控制策略的严格收敛性。最后，对PI控制、滑模控制以及所提出的控制方法进行了对比仿真和实验设计。结果表明，该方法具有较好的鲁棒性和控制性能。
