摘要

针对钢球磨煤机(球磨机)制粉系统多变量、强耦合、非线性、大滞后的复杂控制对象难以建立准确的数学模型

以及常规PID解耦控制算法控制效果不理想等

提出了专家模糊PID解耦控制方法

该控制方法能够对PID参数进行实时整定

可适应球磨机制粉系统在不同工况下的控制要求。以略阳电厂球磨机制粉系统为对象

对球磨机专家模糊PID解耦控制系统进行了仿真验证。结果表明

该控制系统控制品质较好

能够适应球磨机制粉系统在不同工况下PID参数的实时调整

具有较好的控制效果

控制性能和鲁棒性均优于常规PID解耦控制。

Abstract

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.
