Research Of Intelligent Controller Of Electric Actuator

Electric actuators have been used to the oil, chemical, energy, metallurgy, environmental protection and other areas of industrial production processes. It is the nerve center of the process control system. electric actuators have been abroad to achieve a computer, intelligence, digital, communications and multi functional features.The research of the domestic and foreign electric actuator status and development trend of applications, from the electric actuator of the intelligent controller technology theory, puts forward a microcomputer, digital, intelligent technology solutions. AVR microprocessor chip designed to the core of the control circuit, thyristor drive circuit, A/D converter circuit, Hall valve digit detection circuit, LCD circuits, multiple protection circuit, and the details of the hardware system's architecture.Using C language programming and modular structure designed to control the process, including logic control algorithm, regular interrupt drivers, A/D data collection and conversion, remote control and display parameters, fault diagnosis, discusses the closed-loop control system for valve position the working principle.Commissioning and running by machine to achieve a closed-loop control of valve opening, valve-digit test feedback, on-line parameter remote control and display functions, to prove the effectiveness of the controller design.
