Research of Monolithic Microcomputer's Fuzzy Control Technique for Frequency Conversion Screw Pump inViscous Oil Production

The working principle, structure and strategy and carried out means of the monolithic microcomputer fuzzy control system of the surface - ground screw pump torque are discussed. The system has more advanced performance, higher reliability and flexibility than simulated control fashion. Moreover, it has self- diagnostic function. The pump inspection period may be prolonged and the oil output can be increased and management level will be improved with the application of this technology for the torque contrl on polished rod of the screw pumps.
