Adaptive Fuzzy PID Control Design and Simulate of Main Steam Temperature of Power Plant

Abstract

Large-scale thermal power units in the main steam temperature as the controlled object with a large delay, large inertia, nonlinear and time-varying characteristics, leads to its control difficult, and make traditional PID control method is difficult to achieved good. Fuzzy systems articulate knowledge, reasoning similar to the human mind the advantages of fuzzy PID control strategy is proposed and used as a powerful mathematical ability of fuzzy PID control system simulation, the result indicate the fuzzy PID algorithm has the ability of fast, immunity, and robust.
