Abstract:
A method of optimizing performance parameters of a switched reluctance motor comprising:ascertaining optimum performance of objective parameters of at least three objectives of the motor; each as a function of at least one control parameter, said objective parameters of at least three objectives of the motor selected from the group consisting of turn-on angle, turn-off angle, power on the shaft of the motor, drive efficiency, torque ripple coefficient, output torque, torque per rms (root-means-square) current per cycle, torque per mean ampere, energy consumption, phase target current level, hysteresis band size, duty cycle, DC voltage and zero-volt control loop; plotting the parameters on an x-y or x-y-z chart; mapping all of the desired parameters on to one chart as a function of the at least one control parameter and thereby ascertaining the optimum performance of the at least three objective parameters with respect to the at least one control parameter; and the objective parameters include torque ripple coefficient drive efficiency and power in the shaft of the rotor and the at least one control parameter comprises turn-on angle and turn-off angle.
