Abstract
A haptic-enabled system, non-transitory computer-readable medium, and method for controlling a haptic actuator are presented. The haptic-enabled system comprises the haptic actuator, a movement sensor, and a control circuit. The control circuit is configured to: generate a driving portion of a drive signal; apply the driving portion of the drive signal to the haptic actuator to generate movement of one or more portions of the haptic-enabled system; determine (e.g., measure) the movement of the one or more portions of the haptic-enabled system; determine a time-varying correction signal for reducing the movement; generate a braking portion of the drive signal based on a combination of the time-varying correction signal and a defined offset; and apply the braking portion of the drive signal to the haptic actuator. Numerous other aspects are provided.
