摘　　要：针对已有电机控制方法存在的动态响应时间过长、参数控制精度较差等问题,提出基于MCU技术的同步抽蓄电机高精度自动化控制研究。选取STM32F103T4U6型号MCU,并对其引脚进行自定义,将传统PID控制算法改进为非线性PID控制算法,并构建其非线性增益函数。应用MCU执行非线性PID控制算法,即可获得电机电流、速度与位置的非线性反馈控制律,从而实现同步抽蓄电机的高精度、自动化控制。测试结果显示,设计方法应用后同步抽蓄电机控制动态响应时间最小值为60 s,电机速度控制结果达到了目标数值,且无超调现象发生。Aiming at the problems of the existing motor control methods such as too long dynamic response time and poor parameter control accuracy,a high precision automatic control of synchronous pumping and storage motor based on MCU technology is proposed.STM32F103T4U6 MCU is selected and its pin is customized,the traditional PID control algorithm is improved to nonlinear PID control algorithm,and its nonlinear gain function is constructed.The nonlinear feedback control law of motor current,speed and position can be obtained by using MCU to implement nonlinear PID control algorithm,so as to realize high precision and automatic control of synchronous pump and storage motor.The test results show that the minimum dynamic response time of synchronous extraction and storage motor control reaches 1 min after the application of the design method,and the control results of motor speed reach the target value,and no overshoot occurs.
