Analysis of PI Controllers with Anti-Windup Techniques on Level Systems
Authors: , , , ,
Abstract: The actuator element saturation for a long period of time can force high overshoot peaks in the physical system, in most cases, due to the integral action. Taking this effect into consideration, this work aims to present a case study considering this situation applied on a SMAR didactic level system, where an Anti-Windup Technique (AWT) with 5 distinct classic Proportional-Integral (PI) controllers were implemented. To validate its effectiveness, the results were always presented with the comparison of the use with and without AWT controlled responses. Also, the tests were carried out through implementations in MATLAB software, where the results showed a high necessity to use AWTs in these kind of systems. As for the controller’s tuning method efficiency, the integral of squared error index proved that the Cohen-Coon and Ziegler-Nichols controllers showed better results
