摘要： Disclosed herein is a torque control method for a high-speed Switched Reluctance Motor (SRM), which controls a torque in the high-speed operation of a 2-phase SRM. In the torque control method for a high-speed SRM, a positive torque (T*mA) of an active phase (A phase) of the two phases of the SRM is compensated for based on a negative torque attributable to an inactive phase (B phase) of two phases during a compensation control enable interval (ENA) ranging from a time point at which the active phase (A phase) is turned on to a time point at which tail current of the inactive phase (B phase) remains. Accordingly, the present invention can remarkably reduce a torque ripple occurring in high-speed operation mode in consideration of the influence of a negative torque attributable to tail current.

摘要： Disclosed is a method for suppressing a speed ripple occurring during an operation of an AC motor by using a torque compensator based on an activation function. The method includes the steps of calculating a speed error ωerr based on a reference speed ωref and an actual speed ωact; calculating a controller output Trm by using the speed error ωerr as an input of a PI control and an operation of a compensated torque Tcom; and determining a torque variation based on the controller output Trm and a reference torque Tref and operating the torque variation in relation to an anti-windup gain Ka to use torque variation as an input of an integral (I) control. The method suppresses the speed ripple by compensating for the torque ripple through a controller which calculates the compensated torque by taking the signs of the speed error and the differential speed error into consideration.

摘要： Disclosed is a hybrid pole bearingless switched reluctance motor (BLSRM). The BLSRM includes a stator provided with windings, a rotor rotating about an axis when current is conducted to the windings. The rotor includes a plurality of rotor poles extending radially outward, and the stator includes a plurality of stator poles extending radially inward. The windings include suspending windings to generate radial force for the rotor and torque windings to generate torque. The suspending windings are mutually separated from the torque windings. Through the use of the hybrid pole BLSRM, a stator pole generating the radial force can be controlled independently from the stator pole generating the torque by separately arranging the stator pole generating the radial force and the stator pole generating torque based on the analysis of radial force and torque characteristics according to the position of the stator poles.
