Mathematical Model and Simulation of the Industrial Steam Turbine Control System Based on PLC

The control system of industrial steam turbine based on Program mable Logic Controller(PLC), in which we select PLC as the core of the control system, is developed for the characteristic of industrial steam turbine. Based on these researches, the mathematical model of the control system is established. According to the mathematical model, the simulation of the system is performed by means of Simulink in Matlab. The result of the simulation shows the system can work steadily,and have well static and dynamic characteristic.
