A Novel Pid Controller Design Technique For Load Frequency Control

A PID tuning method for load frequency control (LFC) of Power system discuss in this paper. The tuning method is based on the Ziegler-Nichols (ZN), Tyreus-Luyben(TL), Internal Model Control (IMC) and Direct Synthesis(DS) method. Our purpose in this study is comparison of these tuning methods for single input and single output (SISO) system using Matlab simulink and comparatively analysis of performance evaluation of different controller. Such as percentage of Maximum overshoot, Settling time, Rise time, Peak time has been used as the criterion for comparison of SISO system and these tuning methods have been implemented for FOPDT(First-order-plus-dead-time) model, SOPDT(second-order-plus-dead-time) model and higher order system
