SYSTEMS, METHODS, AND APPARATUS FOR CONTROLLING BI-DIRECTIONAL SERVO ACTUATOR WITH PWM CONTROL

摘要

Certain embodiments of the invention may include systems, methods, and apparatus for controlling bi-directional drive current through an actuator. The method may include receiving a direction control signal, manipulating one or more devices to establish at least one switchable positive current path or at least one switchable negative current path through an actuator based at least in part on the direction control signal, providing feedback based at least on current associated with the actuator, and controlling the current based at least in part on the feedback. The method may include manipulating one or more devices to establish at least one positive current path and at least one negative current path through an actuator via pulse width modulation control.
