SYSTEM AND METHOD FOR CONTROLLING FOUR-QUADRANT OPERATION OF A SWITCHED RELUCTANCE MOTOR DRIVE THROUGH A SINGLE CONTROLLABLE SWITCH

摘要

A drive system for regulating the speed of a two-phase switched reluctance machine (TPSRM) rotor may include a speed control feedback loop component that uses an established speed control signal and a signal indicative of the rotor's speed to dynamically adjust a first parameter and a current control feedback loop component that uses an established current control signal and a signal indicative of the current flowing through a stator winding of the TPSRM to dynamically adjust a second parameter. A control signal for regulating the speed of the TPSRM rotor is produced in accordance with the first and second parameters when the TPSRM is operated in a motoring mode, and the control signal for regulating the speed of the TPSRM rotor is produced in accordance with the second parameter but not the first parameter when the TPSRM is operated in a braking mode that converts mechanical energy into electrical energy.
