Abstract: 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.

Abstract: Disclosed herein are an initial driving apparatus and method of a two-phase switched reluctance motor (SRM). The initial driving apparatus of a two-phase SRM includes: a driving unit; a current measuring unit; a memory; and a controlling unit comparing the currents measured in the current measuring unit and a difference between the currents with the data currents and the difference between the data currents stored in the memory to determine an initial position, thereby initially driving the SRM. Therefore, the two-phase SRM may be stably operated.

Abstract: Disclosed is an active boost power converter for driving a single-phase SRM, capable of rapidly establishing excitation current in the excitation mode and reducing tail current and negative torque in the demagnetization mode under the high-speed operation of the SRM. The active boost power converter includes a boost module and a converter module connected to the boost module. The boost module includes first and second capacitors, first and second diodes and a switch device turned on/off to connect the first and second capacitors to each other in series or parallel. The switch device includes an insulated gate bipolar transistor (IGBT). The power converter is operated with first and second input modes and first and second output modes. Voltage of the first capacitor is equal to dc-link voltage and first and second capacitors are controlled to be operated in series or parallel by simply controlling the IGBT.
