Abstract
Disclosed is an improved solenoid actuator utilizing an actuator position sensor which in combination with an actuator controller, adjusts the energizing current supplied to the actuator's coil. The adjustment is based upon any difference between an actual position of the actuator and a desired position of the actuator. If there is a difference, the controller changes the energization of the actuator's coil so as to actively move the actuator to the desired position. The improvement can be utilized with existing rotary and linear proportional actuators as well as any other solenoid-type actuator.
