| 中文摘要:针对较低分辨率位置传感器的无刷直流电机（BLDCM）调速控制问题，以离散滑模控制器为基础，提出了一种变采样的离散滑模控制器。该控制器将通过位置传感器获得的采样时间、速度误差以及负加速度值输入到离散滑模控制器，离散滑模控制器根据输入信息输出电流参考值，并通过电流环地提高无刷直流电机的动态响应能力，而且可以抑制固定采样离散滑模控制器的抖振现象。通过实验验证了所提方法的正确性和可行性。 |

| Design of the Discrete Sliding Mode Controller Based on Variable Sampling of Brushless DC Motors |

| Abstract:Based on the traditional discrete sliding mode controller, a variable-sampling discrete sliding mode controller is proposed for a low resolution position sensor with a brushless DC motor （BLDCM）. The sampling time, the velocity error and negative acceleration obtained from the position sensor are input into the discrete sliding mode controller, which gives the reference current value according to the input information and enhances the dynamic response ability of the BLDCM by current loop and suppresses the chattering phenomenon of the fixed sampling discrete sliding mode controller. The correctness and feasibility of the proposed method are verified by experiments. |
