摘要
在直流无刷电机调速系统中,针对比例积分控制器的速度环通常面临着超调和振荡问题,提出一种PI控制的优化控制算法,将速度环控制器中比例项移到反馈通道,构成基于IP控制器的速度环。对比PI控制器特性,该方法减小传统PI控制器中微分项的作用,抑制了速度环的振荡因素,电机可以获得无超调的速度响应,且抗扰动能力较强。仿真结果表明了该优化方案有效性,且具有简单易实现优点,可以良好的调速性能。
In the speed control system of the brushless dc motor,the speed loop of the proportional integral controller is usual⁃ly faced with the problem of oscillation.A PI control optimization control algorithm is proposed to move the proportion of the speed loop controller to the feedback channel to form the speed loop based on IP controller.Compared with the characteristics of PI control⁃ler,this method reduces the effect of the differential term in the traditional PI controller,inhibits the oscillating factor of the speed loop,and the motor can obtain the speed response without overshoot,and has strong anti-disturbance ability.The simulation results show that the optimization scheme is effective,simple and easy to implement,and has good speed regulation performance.
