Abstract
A method and system that control a driving system to generate driving signals comprising a sequence of full bridge outputs to control an output velocity of at least one at least partially resonant actuator device. The drive system is adjusted to modify a width of one or more pulses of one of the full bridge outputs for a first range of gain or another one of the full bridge outputs for a second range of the gain to less than fifty percent of a period of the fixed drive frequency of the driving signals to achieve a new gain. The adjusted driving signal is provided to the at least one at least partially resonant actuator device.
