Abstract
An electronic device may include a haptic actuator that may include a housing and a field member movable within the housing, and a driver capable of driving the haptic actuator and sensing at least one of a drive voltage and drive current for the haptic actuator. The electronic device may also include a closed-loop controller cooperating with the driver. The closed-loop controller may be capable of determining a calibration of the haptic actuator based upon at least one of the drive voltage and drive current, storing a reference pattern of movement for the field member, and driving the haptic actuator in a closed-loop configuration based upon the calibration of the haptic actuator and reference pattern of movement of the field member.
