Directing against the complex control object

i.e.ball mill coal-pulverizing system with multi-variables

strong coupling

non-linearity

and large time-delay etc.

it is difficult to establish an accurate mathematical model

as well as the effectiveness of conventional PID decoupling control algorithm isn't ideal

an expert fuzzy PID decoupling control method has been put forward.By using the said method

the real-time setting for PID parameters can be carried out

being suitable to requirements of control under different operating conditions of the ball mill coal-pulverizing system.Taking the ball mill coal-pulverizing system in Lüeyang Power Plant as an object

emulation verification of said expert fuzzy PID decoupling control system has been carried out.Results show that the control quality of said control system is better

being suitable to real-time adjustment of PID parameters under different operating conditions of the ball mill coal-pulverizing system

boasting better control effectiveness

and its control performance and robustness being better than that of conventional PID decoupling control.
