Abstract
A method of controlling a device having restricted movement. A controller is provided for controlling the operation of the device using a control algorithm. A normal operation control method is programmed onto the controller and is selectively activated by the controller to generate a normal control signal. A forcing control method is also programmed into the controller and selectively activates a forcing control signal. The normal operation control signal provides regular operation of the device, while the forcing control signal causes the device to operate in a manner that will correct the operation of the device when a restricted motion of the device is detected.
