摘要： A system for controlling a speed of a pump jack system having a variable speed prime mover includes a sensor attached to the pump jack system. The sensor is capable of detecting an absolute position of a first component of the pump jack system relative to a second component of the pump jack system and configured to send a signal proportional to the sensed absolute position and/or velocity and/or acceleration. The system includes process circuitry configured to accept the signal and perform a calculation related to absolute position and/or velocity and/or acceleration of the first component relative to the second component. The system includes a controller that is configured to receive the signal from the process circuitry and configured to send a signal to the prime mover to adjust a rotational speed of the prime mover and the position of the first component relative to the second component.
