N2 - It is known that higher torque capability and less torque ripple cannot be obtained at the same time for flux-weakening control of induction motor in voltage extension region (outside the inscribed circle but within the hexagon). Therefore, a tradeoff strategy for maximum toque and suppressed torque ripple is necessary. Meanwhile, in many previous research studies, VCFS (voltage closed-loop flux-weakening scheme) based voltage extension methods rely on the reconstructed voltage, which means the control performance is affected by the accuracy of reconstruction algorithm and the stability of DC-Link voltage. In this paper, an optimized flux-weakening controller is proposed with the following features: a proper balance between torque capability and torque ripple, an enhanced DC-Link overvoltage rejection and a better torque performance for load change conditions. Simulation and experiment results verify the validity of the proposed scheme.
