摘要： A method of controlling an electric motor that generates an output current from an input voltage command that includes a sum of a first voltage command and a second voltage command is provided. The method receives the output current from the motor as a feedback. The method determines a first set of gain factors to generate the first voltage command based on the feedback such that the input voltage command causes the motor to generate the output current with reduced influence of variations of a set of operating parameters of the motor. The method determines a difference between the feedback and a desired current. The method determines a second set of gain factors to generate the second voltage command based on the difference such that the input voltage command causes the motor to generate the output current as a first, second or higher order response.
