Study on Inverse System of permanent magnet synchronous motor by decoupled Fuzzy Sliding Mode Control

On the basis of the Inverse System theory and Fuzzy Sliding Mode Control, this paper studies on Dynamic Decoupling Control of permanent magnet synchronous motor (PMSM), and a new sliding mode control strategy of fuzzy reasoning has been presented. According to the dynamic mathematical model of PMSM's speed regulation system, the existence of its inverse system is proven, and the design method of fuzzy sliding mode controller for PMSM's decoupling inverse system is given. Simulation result shows: Without increasing the chattering of Sliding Mode, this control strategy can effectively enhance the resistance to load disturbance of the system, and can realize good dynamic and static performance of the PMSM's control system.
