It is important to reduce the vibrations of an Interior Permanent Magnetic motor that is generally installed in electrical vehicles, fuel cell vehicles, and hybrid electrical vehicles. The purpose of the study here is to build up the torque ripple reduction methodology by controlling the working currents on IPM motor. The distributed winding IPM motor with 48 teeth on the stator and 4 pairs of poles on the rotor is treated. The relating equation between torque and three phase alternating currents is shown firstly, utilizing the torque that results from the Finite Element Analysis of the plane electromagnetic field. Secondly, high order currents are derived from the equation and superposed on the basic currents in order to reduce the torque ripple. Finally, the plane electromagnetic field analysis is performed again with the currents including the high order ones and a torque ripple reduction of more than 25 dB with a torque drop of 2.2% is obtained.

Reduction of noise in a car cabin due to road irregularities has been a subject of research for many years. For reducing such a noise, we propose the H2-based Active Structural Acoustic Control (ASAC) method that uses detailed acoustic models obtained by system identification, from the actuators and the shakers to the driver's ears sound pressure level. During experiments in a semi-anechoic room with a compact car, we verify the effectiveness of the proposed approach by obtaining overall noise reduction over the frequency range of 80∼400Hz at the driver's ears.
