Implementation of fuzzy sliding - mode position controller with rule adaptation for permanent magnet synchronous motor drive

Abstract In this paper the model of permanent magnet synchronous motor drive system described by vector control approach. Because of high band width of the interior current control loop, only mechanical dynamics are used to design the outer position controller. The proposed position controller is of fuzzy sliding- mods type with rule adaptation that dose not need the complicated model of the system and compared with the previous works, the proposed method has lesser computations and better performance. Then a simple algorithm for initial rotor position with 15 electrical degree precision is proposed. Finally the practical results are presented to verify the effectiveness of the proposed method.
