This paper deals with the problem of designing a robust dynamic output feedback controller for the wind machine. This paper for the first time exploits the designing controller problem of the wind turbines in the presence of time varying delay and uncertain parameters. In this paper, a novel algorithm is proposed which designs a proper controller based on the idea of Lyapunov Krasovskii functional and Finsler’s Lemma. To validate the result of the proposed algorithm, comparative simulation examples are given which are two different dimension turbines to investigate the performance of the design methodology as compared to those of previous approaches.
