摘要
Most of PID controllers could not work well due to its parameters, so a PID parameters' self-adjusting method, modified A-H arithmetic, was introduced. This method can adjust the PID parameters very well. It adjusts PID controller's parameters by cross point of object's Nyquist curve and negative imaginary axis. It has good identification result to time-delay process. We used it in evaporation procedure's control successfully and effectively. The result shows that this parameters' adjusting method of control system can work in an optimal state and has practical significance.
