Abstract:

This paper takes the first station of heat exchanger for heating network as an example. Because of the properties of nonlinear, large inertia, pure time – delay, it is controlled by the master slave control system based on double S7-200PLC. The accurate control of the outlet temperature of heat exchanger was realized by fuzzy PID control algorithm. The MATLAB simulation results show that the system has high control precision that it can be satisfied with the demands.
