IMPLEMENTATION OF CONTROL AND MONITORING SYSTEM ON PLC FOR INDUSTRIAL STEAM BOILER

Applying our earlier work, we present a practical application in industry, including the numerical method to identify technological processes based on the “cleft-over-step” algorithm [1, 2], and the robust-based control theory to tune the PID (proportional integral derivative) controller [3-5]. These studies are implemented into an industrial boiler control system using a PLC (programmable logic controller). To do this, we design and program in detail a control and monitoring system for a CFB (circulating fluid bed) industrial boiler, including control software and operating interface on the Siemens PLC S7-1200. When equipped with this control and monitoring system, industrial boilers can be operated fully automatically, allowing operators to control and monitor at the control room and intervene remotely when necessary.
