  • Determination of hysteresis controller band for IPMSM-based drive system
    Patent number: 9065362
    Abstract: Methods of providing a control band for a hysteresis controller are presented. A method can determine a control band analytically to avoid the time and costs associated with manual calibration of a hysteresis controller. By way of example, a method can include modeling a machine output, such as stator flux or machine torque, modeling the variation rate for the machine output, and providing a control band based on the variation rate modeling.
