传统PID的整定方法Z-N法，有助于大家快速整定参数，一起讨论哦-The traditional PID tuning method ZN method to help you quickly tuning parameters, and discuss Oh

用z-n法对一个控制过程进行PID参数整定，在simulink平台上进行仿真。-simulation with simulink

临界比例度法自整定PID参数，需要连接相关PID程序即可完成整定(The critical proportional method self-tuning pid parameter, need to connect the related PID program can complete the setting)
