A Comparison and Implementation of ZN, ISE, IMC and ITSE Tuning Methods for PID Controllers
Abstract
Either due to uncertainty or external or internal disturbances, a system may become unstable, or if it is already unstable then to make it stable, we require to design a controller. In this paper, four methods to achieve controller tuning parameters are implemented and compared with each other and some results are achieved after implementation. Ziegler Nichols, Iterative square error, Integral mode control and integral of Time Multiply Squared Errormethods are implemented in Matlab software and results are achieved and time domain specifications are compared. Three of the mentioned methods are minimum error criteria methods.
