Tilt Integral Derivative control for two-area load frequency control problem

This paper investigates the application of tilt integral derivative (TID) control as a supplementary controller for two-area thermal-thermal systems. The purpose of using TID control in AGC systems is to propose an improved feedback loop compensator, which possesses the merits of conventional PID control and offers better and optimal response. The paper utilizes the integral square error (ISE) performance index to form an objective function and a constrained non-linear minimization (CNM) optimization technique for evaluating the objective function. Hence, optimal values of controller parameters are obtained which offers a favorable operating condition for the system. A comparison of dynamic response of AGC systems with proposed TID control and PID control approach reveals that proposed TID controller is capable of delivering better performance.
