摘　　要：针对流量控制系统具有时变性和滞后性的特点,设计了一种模糊控制算法,利用MATLAB中模糊控制工具箱对该算法进行仿真研究,并做了与传统PID控制算法的效果对比试验。仿真结果表明,基于模糊控制算法的流量控制系统超调量小,且动态性能和稳定性均优于传统PID控制算法。In view of the time-varying and time-delay characteristics of the flow control system, a fuzzycontrol algorithm was designed. The model was created in simulink toolbox of matlab for simulation. Thefunction characteristics of PID control and fuzzy control were compared. The results showed that the flowcontrol system based on fuzzy control not only had small overshoot; but also surpassed PID control in thedynamic performance and stabilization.
