A control system for a linear actuator having an electric motor drawing a
variable current level during operation. The control system includes a
current level sensor for determining an operational current level of the
linear actuator and a controller for generating a drive signal and a
force request signal representative of a desired current level of the
linear actuator. The drive signal remains constant during a predetermined
time interval of the controller. The control system further includes a
current limiting component for receiving the force request signal, the
current level of the linear actuator and the drive signal. The current
limiting component minimizes the current level of the electric motor in
response to a comparison between the force request signal and the desired
current level within a time interval substantially smaller than the
predetermined time interval of the controller.
