ABSTRACT:
Apparatus and method for controlling dither in a solenoid actuator. Circuitry produces a frequency command signal in response to a measured dither parameter and produces a current command signal. A solenoid actuator input signal is delivered to a solenoid actuator, said solenoid actuator input signal having a frequency determined in response to the frequency command signal and a magnitude of current determined in response to a current command signal.
