Performance analysis of Permanent Magnet Assisted reluctance

Abstract. This thesis is about the dynamic control of a permanent magnet assisted reluctance synchronous machine (PMA RSM).The PMA RSM in this thesis is a 110 kW traction machine and is ideal for the use in electrical rail vehicles. For accurately analyzing the dynamic characteristics paper is of the of a permanent magnet assisted reluctance synchronous machine, For the body of machine, the paper carries on the finite element analysis of its D-Q axis flux linkage, the self inductance, the mutual inductance. The mathematical model of the Permanent Magnet Assisted reluctance synchronous machine is derived and explained in physical terms from analytical data. To improve the dynamic performance of the PMA RSM, a load torque observer with compensation current feedback is investigated. The derivation of the load torque observer and the detail designs of the observer elements are given. The accurate simulation model of the PMA RSM is used to verify the operation of the observer structures and to evaluate the dynamic performance
