In view of the nonlinear coke oven temperature control system,the cascade control method is proposed with fuzzy PID control.The gas flow adopts proportion control and the temperature adopts fuzzy PID control.When the external control condi-tions are stable,the cascade control system is relatively stable.When the temperature or the gas flow changes,the control system can adaptively adjust,and eventually reach a stable state.The simulation models of PID control and fuzzy PID control are made by MATLAB.And the simulation analysis is carried out under the conditions of no noise and noise,the fuzzy PID control has the small overshoot,the steady state error,the fast response speed,the short adjustment time,the strong anti-jamming ability,and the better control effect.
