摘要

传统的核电站蒸汽发生器水位控制器难以实现全工况范围内的控制效果。对此

提出了一种基于遗传算法的蒸汽发生器水位动态滑模控制方法

设计了具有工程实际意义的动态滑模控制器(SMC)

通过MATLAB仿真实验

考察了该滑模控制器的水位控制效果

与传统PID控制器进行了对比验证了其抗干扰性能。结果表明:基于遗传算法的滑模控制器反应速度快

调节时间短

加入阶跃信号之后也能很快地跟随并稳定;加入干扰信号后

滑模控制器在全工况下的控制效果平稳迅速

具有较强的抗干扰能力;在低负荷工况下

该滑模控制器同样具有反应速度快的特点。

Abstract

The conventional water level controller for nuclear steam generator is challenged in all working conditions variations.Thus

a nonlinear steam generator sliding mode controller based on genetic algorithm was proposed with easy engineering implementation in this article.Through MATLAB simulation test

the water level control effect of this sliding mode control methodology was observed

and its anti disturbance ability was verified.Moreover

performance comparisons between this sliding model controller and the conventional PID controller were carried out.The results indicate that

compared with the conventional PID controller

the proposed sliding mode controller based on genetic algorithm possesses a more stable rapid tracking reaction and potential in anti-disturbance within the whole working conditions.The proposed controller also has faster response characteristics and shorter regulating time under low power condition

which has positive engineering application significance.
