ABSTRACT:
A controller for a motor and a method for controlling the operation of the motor. The controller includes a model of the motor, where the model is utilized to determine modeled values of first and second motor variables. An estimated value of slip is adjusted based at least in part on a comparison of the modeled value of the second motor variable and an estimated value of the second motor variable which is based at least in part on a value of bus voltage and a value of bus current. As the estimated value of slip is adjusted, the modeled values are updated and the voltage utilized to energize the motor is thereby updated to provide control of the motor based on the control of the first motor variable.
