针对PID控制器参数整定优化过程繁琐、难度大等缺点,提出了一种快速获取PID控制器参数的方法。该方法利用直流电机的电压平衡方程以及转矩平衡方程式获取传递函数表达式,通过人群搜索算法(SOA)以PID控制器的三个参数为搜索对象,经过多次迭代寻优,获取直流电机控制系统的最优控制参数。软件仿真结果表明,利用SOA可以快速获得PID控制器的各项参数。相比于传统算法,该算法获取PID控制器的参数方法简单,系统具有更强的鲁棒性且响应速度快,为直流电机PID控制器参数整定优化提供了参考依据。

To address the issue of the complex and difficult of the PID controller parameter tuning optimization process,a method for quickly obtaining PID controller parameters is proposed.This method uses the voltage balance equation of the DC motor and the torque balance equation to obtain the transfer function.The three parameters of the PID controller are searched by the Seek er Optimization Algorithm(SOA).After multiple iterations,optimal control parameters for DC motor control systems are obtained.The effectiveness of experimental results show that parameters of the PID controller can be quickly obtained by using SOA.Com pared with the traditional algorithm,this algorithm is more easier,and it has more robust and more fast response speed,which pro vides a reference for the tuning of the DC motor PID controller parameters.
