Abstract
Systems and methods to manipulate the noise and vibration of a switched reluctance machine (SRM), capable of being implemented in a controller. By use of vibration sensors and a real-time optimizer, the noise and vibration profile of an SRM and associated load can be modified in order to meet multiple control objectives, such as torque ripple mitigation (TRM), harmonic spectrum shaping, and efficiency improvement. The systems and methods can be adapted to high power, high pole count, and high speed applications, and applications where electrical or mechanical imbalance exists.
