Through study on PID type fuzzy controller

the high inertia and large delay of main steam temperature

as well as the features of difficulty in establishing precise numerical model

an adaptive fuzzy control method has been put forward

making the fuzzy control system to have stronger adaptive capability through on-line regulation of the adjustable factors and continuous optimization of the controlling process.Taking the control system of main steam temperature as an example

an emulation of the PID type adaptive fuzzy control method has been carried out

and a comparison with the fuzzy PID control being made.Results show that the said method has substantially improved the dynamic property

the steady state precission

and the robustness of said control system.
