this the matlab tuning of pid with root locus

It is a M-file Matlab code useful for PID controller design via root-locus method.

针对双容水箱大滞后系统，采用PID方法去控制。首先对PID控制中各参数的作用进行分析，采用根轨迹校正、伯德图校正的方法，对系统进行校正。最后采用神经网络PID控制的方法-Large time delay for two-capacity water tank system, using PID method to control. First, the parameters of the PID control in the role of analysis using root locus c
