摘要:
针对开关磁阻电机的调速控制系统的起动方式和速度控制开展研究,采用两相绕组通电起动的方式,以增大转矩、减小转矩脉动。提出了模糊–自适应整定PID控制算法,并以STM32 + FPGA为主控制器,应用低速电流斩波、高速角度位置控制方式设计了开关磁阻电机调速系统。对于解决超调量高、动态响应慢的不足、精确度不高的问题有一定的效果。实验结果表明,系统转速的精确度在10 r/min之内,最大超调量为15 r/min。
Aimed at research on starting mode and speed control of switched reluctance motor speed control system, a two-phase starting is adopted to start the electric, in order to increase the torque and reduce the torque ripple. A fuzzy adaptive PID control algorithm is proposed, and a switched reluctance motor speed control system with STM32 + FPGA as the main controller is designed, applying current chopping in low speed and angle position control mode in high speed, which has a certain effect on solving the problems of high overshoot, slow dynamic response and low accuracy. The experimental results show that the precision of the system speed is within 10 r/min, and the maximum overshoot is 15 r/min.
