Abstract:
1. A system to control an air management valve, comprising: said air management valve, including at least one feedback sensor, and, an actuator; a sensor operable to determine a commanded input; and, a control scheme, operable to: monitor a position of the air management valve using the input from the feedback sensor, determine an error term, based upon the monitored position of the air management valve and the commanded input, and, determine an adaptive feedforward term, based upon the monitored position of the air management valve, a characterization of the air management valve, and the error term, wherein the characterization of the air management valve is based upon torque and a direction of movement of the air management valve; and control the air management valve to a desired position, based upon input from the feedback sensor, the adaptive feedforward term, and the sensor operable to determine the commanded input.
