Revisiting the Ziegler-nichols Tuning Rules for Pi Control — Part Ii the Frequency Response Method
نویسنده
چکیده
This paper presents an analysis of the Ziegler-Nichols frequency response method for tuning PI controllers, showing that this method has severe limitations. The limitations can be overcome by a simple modification for processes where the time delay is not too short. By a major modification it is possible to obtain new tuning rules that also cover processes that are lag dominated.

Convenient Almost Optimal and Robust Tuning of Pi and Pid Controllers
T uningrules for PI and PID controllers for stable non oscillating plants are presented. These rules are based on an optimization procedure, where both low frequency performance, mid frequency stability margins and high frequency control activit y are taken into account. The required plant kno wledgeis either a speci c frequency point, like in Ziegler-Nichols frequency design method, or a step ...
متن کاملDesign of PI and PID controllers with transient performance specification
Proportional-integral-derivative (PID) controllers are widely used in industrial control systems because of the reduced number of parameters to be tuned. The most popular design technique is the Ziegler–Nichols method, which relies solely on parameters obtained from the plant step response. However, besides being suitable only for systems with monotonic step response, the compensated systems wh...

متن کاملThe Good Gain method for simple experimental tuning of PI controllers
A novel experimental method – here denoted the Good Gain method – for tuning PI controllers is proposed. The method can be regarded as an alternative to the famous Ziegler-Nichols’ Ultimate Gain method. The approach taken resembles the Ziegler-Nichols’ method as it is based on experiments with the closed loop system with proportional control. However, the method does not require severe process ...

Multivariable liquid level control is essential in process industries to ensure quality of the product and safety of the equipment. However, the significant problems of the control system include excessive time consumption and percentage overshoot, which result from ineffective performance of the tuning methods of the PID controllers used for the system. In this paper, fuzzy logic was used to t...
