摘　　要：以额定功率为100W的三相鼠笼型异步电动机为控制对象,在保证调速性能的前提下尽可能地降低成本,完成以STM32F103ZET6为主控芯片的变频调速控制器设计开发。该调速器采用转速闭环转差频率控制方式,结合正弦脉宽调制(SPWM)技术,实现对转速调节的准确控制。测试结果验证该调速器控制系统的可靠性和稳定性。对于其他功率范围内的交流电机,可以通过重新计算设计参数来实现其调速器的设计。Takes the three-phase squirrel cage asynchronous motor with rated power of 100W as the control object,and on the premise of guarantee?ing the speed regulation performance,reduces the cost as much as possible,the design and development of frequency conversion speed reg?ulation controller with STM32F103ZET6 as the main control chip are completed.The speed governor adopts the speed closed-loop slip fre?quency control mode,and combines the Sinusoidal Pulse Width Modulation(SPWM)technology to realize the accurate control of speed reg?ulation.The test results verify the reliability and stability of the governor control system.For AC motors in other power ranges,the design of their governors can be realized by recalculating the design parameters.
