This paper analyses the cascade PID control system used in the boiler on the main steam temperature system based on the introduction of the importance and control principle of the main steam system of the boiler, and propose a fuzzy PID control system for improving the cascade control system. As a consequence, the MATLAB simulation outcomes show that the system has better control effect and reaction speed, and the hysteresis of the main steam control system in the boiler is improved.
