本文用根轨迹法从理论上分析了PI和PID调节所能达到的性能极限。所得到的结论可用于对各参数整定法进行评价,也可直接用于调节器的整定。
In this paper, the root locus method is used to theoretically analyze the performance limit that PI and PID can achieve. The conclusions obtained can be used to evaluate the parameters of the tuning method can also be used directly for the regulator tuning.
