    摘 要:针对传统建模方式下电机控制性能易受参数摄动影响的问题,提出一种改进型无模型滑模控制方法。建立超局部模型降低控制系统对电机参数的依赖,并结合新型趋近律设计改进型无模型滑模控制器,利用扩展滑模扰动观测器补偿系统未知部分。实验结果表明,该方法响应速度更快,鲁棒性更强。

    Abstract: The motor control performance under the traditional modeling approach is susceptible to parameter variety, so an improved model-free sliding mode control method is proposed. It builds an ultra-local model to reduce dependence of the control system on motor parameters, designs an improved model-free sliding mode controller based on the new reaching law, and adopts an extended sliding mode disturbance observer to compensate the unknown part of the system. The experimental results show that this method is of faster response and stronger robustness.
    Key words: permanent magnet synchronous motor; new reaching law; model-free sliding mode control
