针对传统直流无刷电机双闭环控制系统在高精度控制场合下稳态精度与动态响应不足的问题,基于STM32F405RGT6微控制器,设计一种高精度调速系统.在驱动方案上,利用FOC策略,并结合改进型电流环PR控制器与改进型速度环PI控制器,提出改进型双闭环FOC控制方案.通过负载观测补偿及电流采样、转子位置估计等优化策略对系统进行优化,提升电机在各种工况下的运行可靠性与效率.实验结果表明,所提出的控制系统具有动态响应快、调速精度高、抗负载扰动能力强等优势,可满足现代工业高精度控制的需求.
In allusion to the problem of insufficient steady-state accuracy and dynamic response of the traditional double closed-loop control system of brushless DC motor in high-precision control occasions,a high-precision speed regulation system based on STM32F405RGT6 microcontroller is designed.In the driving scheme,an improved double closed-loop field-oriented control(FOC)scheme is proposed by using the FOC strategy and combining with the improved current loop PR controller and the improved speed loop PI controller.The system is optimized by load observation compensation,current sampling,rotor position estimation and other optimization strategies,which can effectively improve the operation reliability and efficiency of the motor under various working conditions.The experimental results show that the control system has the advantages of faster dynamic response,higher speed regulation accuracy and stronger anti-load disturbance ability,which can meet the requirements of modern industrial high-precision control.
