With respect to the interior permanent magnet synchronous motor(IPMSM)
this paper gives a mathematical model in d-q frame
and based on space voltage vector pulse width modulation(SVPWM) analyzes the stator current optimal control strategy of IPMSM.The maximum torque/current(MTPA) and open-loop flux-weakening control algorithms are adopted.Moreover the implementation method of the reference current regulator and current decoupling controller modules are proposed
