Abstract: An example actuator control system includes an actuator, a plurality of motors configured to cooperatively operate the actuator, and a controller. The controller is configured to determine an output signal for controlling active ones of the motors during a current update cycle based on a first gain value, an integral contribution from the current update cycle, and an integral contribution from a preceding update cycle. The controller is configured to, based on a quantity of the motors that is active differing between the current and preceding update cycles, scale the integral contribution from the preceding update cycle for the output signal determination based on the first gain value and a second gain value from the preceding update cycle. A method of controlling a plurality of actuator motors is also disclosed.

Abstract: Multiple positions within a mechanical system are measured with a plurality of sensors including at least one 4-wire and at least one 5-wire sensor. The 5-wire sensor has two output voltage signals sent to a signal conversion processor, and the 4-wire sensor also sends a signal. A sum is created of the two voltage signals from the 5-wire sensor. An excitation voltage supply supplies a common excitation voltage to both sensors. Feedback of the excitation voltage is measured by the signal conversion processor. The excitation voltage feedback is utilized to ratio-metrically correct a position feedback signal from the 4-wire sensor at the signal conversion processor. The signal conversion processor is able to synthesize a signal indicative of the excitation voltage from the two voltage signals sent from the 5-wire sensor in the event the excitation voltage feedback is not received at the signal conversion processor.
