Abstract

Aiming to the chaotic motion protlem of fractional order direct-driven permanent magnet synchronous generator（D-PMSG） with state time-delay, a fuzzy memory state feedback control strategy is proposed. Firstly, the fuzzy chaotic model of fractional order D-PMSG with state time-delay is established by using T-S fuzzy theory and fractional calculus theory. Secondly, based on parallel distributed compensation（PDC） control technology, a fuzzy memory state feedback controller is designed. Then, by combining Lyapunov stability theory and the properties of fractional calculus, based on Schur complement lemma, the sufficient conditions for the asymptotic stability of time-delay system are given in the form of linear matrix inequality（LMI）. Finally, by using Oustaloup filter, the simulation model of fractional order time-delay system is built to verify the correctness of the model and the effectiveness of the control scheme. The simulation experiments show that compared with the memoryless state feedback controller, the fuzzy memory state feedback controller has better control performance and robustness.
