ABSTRACT:
A control system for an engine throttle valve actuator uses an actuator position feedback loop with a compensation factor which applies a reverse voltage having an amplitude based on actuator momentum to a DC motor to effectuate an electrical braking action to achieve high speed response with positional accuracy. A separate position limiting feedback loop is used to prevent excessive actuator excursions. The engine throttle valve is controlled to a selected position by using a throttle valve position feedback loop and a compensation factor to provide a feedback signal to a summing junction.
