The flux-weakening control is very effective to attain a high-speed rotation of an interior permanent magnet synchronous motor (IPMSM). To increase robustness of the flux-weakening control, we propose a new control method of both a d-axis current and a q-axis current by using a voltage feedback with the sliding mode control. The proposed control archives a high speed rotation against an error and a change of IPMSM parameters. Through a simulation we show an effectiveness of the proposed control method. In result, the parameter adjustment with a load examination machine is not needed.
