摘　　要：针对永磁同步电机传统调速系统稳定性差的问题,提出基于扰动观测器的反步非奇异终端滑模控制策略。应用递推原理设计了反步控制策略,结合滑模控制器和扰动观测器估计系统负载扰动,实现反馈补偿。仿真实验结果表明,与矢量控制算法和传统滑模控制算法相比,文中方法具有收敛速度快、抗外部干扰能力强的优点。In view of the problems of poor stability of the traditional speed regulation for permanent magnet synchronous motor(PMSM),a backstepping nonsingular terminal sliding mode control strategy based on disturbance observer was proposed.The recursive principle was used to design the backstep⁃ping control strategy.The sliding mode controller and disturbance observer were combined to estimate the system load disturbance and realize feedback compensation.The experimental results show that compared with the vector control algorithm and the traditional sliding mode control algorithm,the pro⁃posed method has the advantages of fast convergence speed and strong anti-external disturbance ability.
