数字PID程序，可以实现常规的PID参数整定和系统响应曲线的绘制-digital PID procedures can be achieved by conventional PID tuning and system response curve drawing

PID整定参数的参考方法 很有用的哦 欢迎下载-PID parameter tuning methods useful reference Oh welcome to download

采用微分先行PID控制实现对液位的控制采用增量式PI控制实现流量的快速跟踪且波动范围较采用经验方法分别对上述两个PID控制器参数进行整定。-Of liquid level control is realized by using derivative ahead PID control flow is realized by using incremental PI control of the fast track and the fluctuation range respectively
