基于Matlab的锅炉过热汽温模糊控制系统仿真

System of fuzzy control in superheated steam temperature of boiler based on Matlab

针对电站锅炉过热蒸汽温度PID串级控制系统的效果并非十分理想的现状 ,应用Matlab的模糊推理工具箱 ,设计了锅炉过热蒸汽温度模糊控制系统 ,并用Simulink进行了对比仿真研究 ,结果表明 ,应用模糊控制可获得比使用传统PID控制更为理想的调节效果 ,不论在何种扰动下 ,其综合控制品质指标都比较高 ,动态过渡过程时间比较短 ,基本上可以消除振荡 。

This paper designed simulation of a fuzzy control system in superheated steam temperature of boiler by the mathematical computation tool kit—Matlab. A simulation research was done by a simulation toolbox—Simulink. It was shown that fuzzy control system had a better control of superheated steam temperature than the common PID control system in any disturbance. The dynamic time was short and the amplitude of vibration was small.
