Optimal Speed Control of PMSM for Electric Propulsion Based on Exact Linearization via State Feedback

摘要：

Ship maneuverability requires speed control system for electric propulsion with wide speed range and fast dynamic response. Therefore, nonlinear optimal control design method of permanent magnet synchronous motor for electric propulsion is proposed based on differential geometry in this paper. The nonlinear system model is linearized into double-input and double-output linear Brunovsky form via multi-input state feedback linearization. Afterwards the linear quadratic optimal controller is designed based on the Brunovsky form. The dynamic response and the anti-jamming ability of designed control speed system are studied by simulation technique. The simulation results show that by using multi-input state feedback method based on differential geometry theory, the linear quadratic optimal control system can control permanent magnet synchronous motor with fast transient response and good load disturbance resistance response, which can satisfy the request in ship maneuverability.
