摘要：

A Hysteresis-band instantaneous current control PWM technique is popularly used because of its simplicity of implementation, fast current control response, and inherent peak current limiting capability. However, a current controller with a fixed hysteresis band has the disadvantage that the modulation frequency varies in a band and, as a result, generates nonoptimum current ripple in the load. This paper describes an adaptive hysteresis-band current control method where the band is modulated with the system parameters to maintain the modulation frequency to be nearly constant. Although the technique is applicable to general ac drives and other types of load, an interior permanent magnet (IPM) synchronous machine load is considered. Systematic analytical expressions of the hysteresis band are derived as functions of system parameters. An IPM machine drive system with a voltage-fed current-controlled PWM inverter has been simulated on computer to study the performance of the proposed method. © 1990 IEEE
