基于ARM的无位置传感器BLDCM控制系统设计

摘要

设计了基于STM32F103C8T6和FSB50450S功率模块的无刷直流电机控制系统,实现了转速和电流双闭环直流调速,并将控制系统用于水泵控制中,最终实现满足水泵实际运行的恒速和恒压两种模式的控制算法.并对控制系统进行仿真测试,最后在水泵控制系统平台中完成试验.%A control system was designed for the brushless DC motor based on STM32F103C8T6 and FSB50450S power modules to realize double closed-loop DC regulation of the rotational speed and current.The control system was used in water pump control to meet the requirement of the control algorithms for constant speed mode and constant pressure mode of water pump operation.Furthermore,simulation tests were made on the control system.Finally,a test was completed on the platform of the water pump control system.
