以提升水下航行器低速无刷直流电机调速控制技术水平为目的，提出水下航行器低速无刷直流电机调速控制方法。通过水下航行器低速无刷直流电机数学模型，利用该数学模型输出低速无刷直流电机数学模型调速控制参数，然后设计模糊PID控制参数，利用麻雀搜索算法整定该模糊PID控制参数，通过调节输入值和实际反馈值的偏差，实现水下航行器低速无刷直流电机调速控制。实验结果表明，该方法计算水下航行器低速无刷直流电机电磁功率数值与实际值差值较小，对模糊PID控制参数整定能力较强，并可有效控制水下航行器低速无刷直流电机调速，且响应迅速超调量小，应用效果较佳。
In order to improve the speed control technology level of low-speed brushless DC motor for underwater vehicle, a speed control method of low-speed brushless DC motor for underwater vehicle is proposed. Through the mathematical model of low-speed brushless DC motor of underwater vehicle, the speed control parameters of the mathematical model of low-speed brushless DC motor are output by this mathematical model, and then the fuzzy PID control parameters are designed, and the fuzzy PID control parameters are adjusted by sparrow search algorithm. By adjusting the deviation between the input value and the actual feedback value, the speed control of low-speed brushless DC motor of underwater vehicle is realized. The experimental results show that the difference between the numerical value and the actual value of the electromagnetic power of the low-speed brushless DC motor of underwater vehicle calculated by this method is small, and the fuzzy PID control parameter setting ability is strong, and the speed of the low-speed brushless DC motor of underwater vehicle can be effectively controlled, with rapid response and small overshoot, and the application effect is good.
