Combined feedforward and feedback parameter estimation for electric machines

A method for estimating a parameter of an electric machine, comprising:

• receiving a torque command signal indicative of a desired torque for said electric machine;
• receiving a current value;
• receiving a temperature value;
• and
• wherein said estimating is a resultant of a parameter estimation process responsive to at least one of said torque command signal, said current value, and said temperature value, a resultant of said parameter estimation process representing said parameter of said electric machine.

A storage medium encoded with computer program code;

• said code including instructions for causing a controller to implement a method for estimating a parameter of an electric machine comprising:
• receiving a torque command signal indicative of a desired torque for said electric machine;
• receiving a current value;
• receiving a temperature value;
• and
• wherein said estimating is a resultant of a parameter estimation process responsive to at least one of said torque command signal, said current value, and said temperature value, a resultant of said parameter estimation process representing said parameter of said electric machine.

A computer data signal embodied in a carrier wave, the computer data signal comprising:

• code configured to cause a controller to implement a method for estimating a parameter of an electric machine comprising:
• receiving a torque command signal indicative of a desired torque for said electric machine;
• receiving a current value;
• receiving a temperature value;
• and
• wherein said estimating is a resultant of a parameter estimation process responsive to at least one of said torque command signal, said current value, and said temperature value, a resultant of said parameter estimation process representing said parameter of said electric machine.
