PID Tuning Methods An Automatic PID Tuning Study with MathCad

There are several methods for tuning a PID controller. This paper takes a qualitative look at three common methods, with comparisons of accuracy and effectiveness. These three methods include a guided Trial and Error method, the Ziegler-Nichols method, and the Cohen-Coon method. For an exceptionally responsive system the Trial and Error method is often used after the Ziegler-Nichols or Cohen-Co...

Pid Tuning Rule for Pressure Control Applications

In pressure control applications, servo-valves or variable displacement pumps are used to meter the flow into a supply line or a chamber with relatively constant capacity, thereby controlling its pressure under the influence of disturbances such as flows in and out of the controlled volume. For most applications proportional integral derivative (PID) controllers are suited and widely used in re...

Tuning for Smooth PID Control with Acceptable Disturbance Rejection

The objective of most published tuning rules is “tight” or fast control, subject to avhieving acceptable robustness. This gives a maximum limit on the controller gain. In industrial practice, however, the objective is often “smooth” or slow control, subject to achieving acceptable performance in terms of disturbance rejection. This paper provides the corresponding minimum limit on the controlle...

Adaptive Sliding Mode Control with PID Tuning for Uncertain Systems

The goal is to achieve system robustness against parameter variations and external disturbances. Suitable PID control gain parameters can be systematically on-line computed according to the developed adaptive law. To reduce the high frequency chattering in the switching part of the controller, the boundary layer technique is utilized. The proposed method controller is applied to a brushless DC ...
