通过PID调节器的三个参数寻优,可以使系统的某一时域指标最小。本文介绍一种将时域中的性能指标转化到复域内,再进行寻优的计算方法,从而避免了对系统进行多次仿真,大大提高了寻优速度和精度。 Through the three parameters of the PID regulator optimization, you can make the system a minimum of time domain indicators. This paper introduces a calculation method that transforms the performance indexes in the time domain into complex domains and then performs optimization, which avoids multiple simulations of the system and greatly improves the optimization speed and precision.
