    Abstract: A control system for a rod pumping unit is disclosed herein. The control system includes a memory device, a sensor, and a processor. The memory device is configured to store a velocity profile for controlling a sucker rod string of the rod pumping unit. The sensor is configured to take measurements for determining surface load of the sucker rod string. The processor is configured to gain access to the memory device and the velocity profile. The processor is further configured to determine a reference force. The processor is further configured to receive a measurement from the sensor and determine the surface load. The processor is further configured to compute a desired velocity for commanding the rod pumping unit. The desired velocity is computed based on a reference velocity from the velocity profile, the reference force, and the surface load.

    Abstract: A system for enhancing a flow of a fluid induced by a rod pumping unit is provided. A pumping control unit is configured to control stroke movement of the rod pumping unit. The pumping control unit is configured to store a first set of stroke timing data based on a first pressure level and a second set of stroke timing data based on a second pressure level, store a set of pressure weights, and receive a current pressure level. The current pressure level is between the first pressure level and the second pressure level. The pumping control unit is also configured to determine a current set of stroke timing data based on the current pressure level, the first set of stroke timing, the second set of stroke timing, and the set of pressure weights, and initiate at least one stroke of the rod pumping unit.

    Abstract: A system for controlling an integrated pump and energy recovery system is disclosed. The processor-based device is configured to receive a position signal representative of a measured position of a piston assembly movable between a top dead center and a bottom dead center of a hydraulic cylinder and a pumping cylinder, from the position sensor. The processor-based device is also configured to receive a pressure signal representative of a measured pressure of at least one of a fluid medium fed from the pumping cylinder to a filtering device, a hydraulic fluid fed from the hydraulic pump to the hydraulic cylinder, from the pressure sensing unit. The processor-based device is further configured to generate a control signal based on the position signal and the pressure signal, and transmit the control signal to the hydraulic power unit to control measured position of the piston assembly and a pressure of the fluid medium.
