Patent ID: 8339093

Claim:
A control system for controlling an AC motor drive, the control system programmed to: input an initial voltage-frequency command to the AC motor drive corresponding to a static voltage-frequency profile; receive a real-time output of the AC motor drive generated according to the initial voltage-frequency command; determine a real-time value of a motor parameter based on the real-time output of the AC motor drive; input a plurality of modified voltage-frequency commands to the AC motor drive corresponding to a dynamic voltage-frequency profile; determine the real-time value of the motor parameter corresponding to each of the plurality of modified voltage-frequency commands; identify an optimal value of the motor parameter based on the real-time values of the motor parameter; and maintain an input of a current modified voltage-frequency command when the real-time value of the motor parameter corresponds to the optimal value of the motor parameter, wherein the current modified voltage-frequency command corresponds to a peak value of the motor parameter.
