1.采用微分先行PID控制实现对液位的控制。 2.采用增量式PI控制实现流量的快速跟踪，且波动范围较小。 3.采用经验方法分别对上述两个PID控制器参数进行整定。 (1. Using differential PID control to achieve the first level of control. 2. Using PI control to achieve incremental flow of fast-track, and the fluctuation small. 3. By the empirical methods are two of the PID controller parameters tuning.)
