摘要
为保证直流无刷电机在未知负载下能保持恒定转速,本文采用了滑模变结构控制方法,通过控制直流电机的输入电压,使电机在负载有较大变化时能按照设定速度稳定旋转。仿真实验表明,该控制算法具有动态响应快速、超调量小,以及对外部负载转矩扰动和干扰鲁棒性较强的特点。
In order to keep the constant speed of brushless DC motor under unknown load,the sliding mode variable structure control method is adopted to control the input voltage of the DC motor,the simulation results show that the control algorithm has the characteristics of fast dynamic response,small overshoot and strong robustness to external load torque disturbance and interference.
