Abstract

The main steam pressure control system of boilers has a lot of characteristics, include the large inertia, the highly delay, and the nonlinear and time-varying, there are many disturbance factors in its operation and it is hardly to control. In order to solve this situation, this article integrates the advantages of the Fuzzy Control and the PID control. We design the fuzzy-PI controller by combining the SIMULINK and FUZZY tool box organically. The simulation results show that this control method greatly enhances the control effect of the nonlinear, hysteresis system, and improves the system´s flexibility and adaptability.
