摘要: This paper presents a means to improve the efficiency of interior permanent magnet (IPM) synchronous machine drives which can be best implemented via continuous online self tuning. With this technique an improved maximum torque-per-ampere trajectory for IPM including effect magnetic saturation. shown efficiency. The model-based estimation algorithm is based on commanded voltage and measured current rotor position/velocity. model has two equations where cross-coupled parameters eliminated robustness parameter estimation. Parameter by combining with closed loop observer. suitable performance illustrated experimentation. vector controller using controls motor torque accurately under any load speed.
