Application of Adaptive Tabu Search for Optimum PID Controller tuning AVR System

This paper postulates the ascertainment of offline, optimal proportional-integral-derivative (PID) controller parameters of an automatic voltage regulator (AVR) system using Adaptive Tabu Search (ATS) algorithm. By minimizing the performance index such as integrated absolute error (IAE), the integral of squared error (ISE), and the integral time absolute error (ITAE) employed method, the parameters of this PID controller is acquired. For significant contrast, the classical tuning proposed by Ziegler and Nichols is applying compared with demostrated method. The performance of the proposed tuning mechanism had been demonstrated and analysed in efficient and robust in improving the step response of an AVR system with application to control of synchronous generator excitation system by selecting the suitable performance index.
