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 correction, Bird figure correction method, the system calibration. Finally, neural network PID control method
