ABSTRACT:
A method and system are provided for positioning a gasoline engine throttle in response to an angular position input command signal. A multi-phase variable reluctance motor positions the throttle in response to motor current commands from a micro-controller. The micro-controller receives and processes the position input command and throttle position feedback signals from a multi-phase variable inductance position encoder rotatably coupled with the motor shaft. The motor current command are obtained from look-up tables that are derived from empirical data of the motor. The motor current command tables are a mapping from motor rotor position and desired motor torque to desired motor currents in the appropriate phases of the motor to hold the load.
