为克服稳态偏差

还给出了一种简便的改进方法

即在主蒸汽温度最优反馈策略中增加了稳态偏差判断器和BP网络修正器

仿真结果表明效果良好。

Abstract

Based on optimal feedback control principle

a strategy of optimal feedback control for main steam temperature has been put forward to optimize and resolve the state feedback matrix

realizing rapid and stable followup to setted value of steam temperature by using desuperheating water quantity as little as possible. At the same time

the DID control can be eliminated

and the control system may be simplified. Besides

in order to overcome the steadystate deviation

an improved and simplified method

namely addition of steadystate deviation discriminator and BP network corrector into the optimal feedback strategy for main steam temperature

has been given. Simulation shows that the said method has good effectivenees.
