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.
