Abstract :
This paper presents a novel decentralized robust multi-input-multi-output-proportional-integral-differential (MIMO-PID) load frequency controller based on Iterative Linear Matrix Inequality (ILMI) algorithm for two-area reheat thermal power system in deregulated environment. To improve its robustness to variation in the controlled variables, H∞-norm of the system transfer function is used. Therefore, proposed controller is known as (IPIDH∞). The simulation results show that the MIMO-PID controller is superior to robust H∞ LMI-based output feedback controller.
