Main Steam Temperature Control System Based on Fuzzy Control Scheme

The main steam temperature of power plant is a time-varying, large time delay and big interference thermodynamic objects. It is difficult to control the temperature of the supercritical main steam efficiently through the traditional PID control scheme. A fuzzy-PID control scheme is proposed in this paper. The proposed main steam temperature control system based on fuzzy-PID control scheme was built with Simulink blocks and verified by the simulation results. The simulation results indicate that the proposed fuzzy-PID control scheme can work well and achieve better performances than traditional cascade PID control scheme.
