精选优质文档-倾情为你奉上Boiler level control system based on ControlLogix5550 PLCAbstract-This paper is a research design based on EFPT process control device. In the design, actual industry field has been simulated and corresponding modeling has been carried on for the boiler level system. Then the appropriate PID parameter has been sorted out and ControlLogia5550PLC has been used to control the entire boiler level system.At last, a corresponding control interface has been established and
