Abstract
A system for automatic calibration of an actuator, where the system has an actuator and a computer, and the computer further includes a PID controller. A sensor connected to the actuator transmits values representing the motion of the actuator to the input of the PID controller. The computer is programmed to compare the values representing the motion of the actuator to the output of the PID controller, thus outputting an error signal representing the difference between the output of the PID controller and the values representing the motion of the actuator. The computer stores this difference as a calibrated set point for the actuator when the difference is less than a predetermined amount. This calibrated set point is used to initialize the operation of a machine propelled by the actuator.
