在分析无刷直流电机工作原理和数学模型的基础上,提出了一种基于Matlab的无刷直流电机控制算法建模方法,构建了无刷直流电机控制算法仿真模型。电机控制算法使用位置环和速度环双闭环PID控制,速度计算使用M/T滑动窗口法。仿真结果表明该模型正确有效,且位置控制精度和速度计算精度较高,为设计和验证控制算法提供有效手段和工具。

Based on the operating principle and mathematical model of the Brushless DC motor,a method for modeling of the Brushless DC motor control algorithm was proposed,and simulation model was be established.Not only the control algorithm adopted double loop being composed of the position loop and the speed loop,but also speed calculation adopted M/T method using sliding window.Simulating results show that the model is correct and valid with the high precision of position control and speed calculation and offers a method and tool for designing and verifying control algorithm.
