The maximum torque/cUlTent (MTPA) and open-loop f1ux- weakening control algorithms are adopted. Moreover the implementation method of the reference cUlTent re♂Ilator and cUlTent decoupling controller modules are proposed , on the basis of which a simulation model of IPMSM speed regulation system is constructed in Matlab/Simulink environment , with a large number of simulation experiments having been done. The simulation results indicate that the cUlTent vector trajectory can meet the optimal t1勾ectory trend of stator cUlTent vector , and the
