Abstract
One example embodiment of the present invention is a control system for an actuator that is controlled by a pulse width modulation (PWM) signal. The control system includes at least two controllers that are connected to the actuator. Each of the controller sends an independent sequence of PWM signal to the actuator. The actuator is controlled by a combination of the PWM signals from all the controllers together. The controllers are synchronized by a clock signal that provides a sequence of periodic clock interval and the PWM signal from each controller occupies a separate and non-overlapping clock interval from the PWM signal of other controllers.
