Abstract:This paper researches a sensorless control method of flux-switching permanent linear magnet with high-frequency signal injection on the basis of salient pole verification, through the analysis of FSPMLM structure. A high frequency sinusoidal voltage signal is superimposed into the estimated d-axis, and the mover position can be demodulated after q-axis current is regulated, which is relative to error angle. Ultimately the mover position and speed can be obtained exactly. The paper also contributes to an improved magnetic pole identification based on space vector pulse width modulation for and arbitrary initial position to resolve starting problem of IPMSM. At last, the simulation model of FSPMLM and control system are constructed and all results of simulation demonstrate the accuracy and effectiveness of the presented approach, this method is well suitable for the application. | |||

Abstract:To analysis influences under various fault conditions, a fault model of Flux-Switching Permanent Machine (FSPM) under stator winding shorted turn which can be used for a performance assessment of a diagnostic algorithm is presented. For fault conditions of FSPM, turn-to-turn fault and phase-to-phase fault in stator winding are considered in this paper. Even though the conventional d-q coordinate system can be used to construct the model of FSPM, but d - q coordinate system will have a great error under faults. To overcome this limitation, a fault model of FSPM is derived using multi-loop theory. Inductor parameters are obtained by finite element analysis. The accurate fault model provided in this paper lays the foundation for fault diagnosis. | |||

Abstract:Nowadays motor vector control is applied widely, but in fact motor parameter which has much effect on vector will change at any moment, which affects precision of vector control. A new method is proposed, rotor time constant can be estimated by using torque and flux current and the change of stator and rotor flux angle. Simulation show the method can compute instantaneous parameters and improve precision of vector control. | |||
