摘要
在二维模糊控制结构的基础上,针对主汽温具有影响因素多、时滞较大及模型时变的特点,提出了一种双模模糊串级控制设计方法,既保留了串级控制抗内扰的性能,又融入了模糊控制动态性能好的特点。通过仿真,与串级P ID控制比较,该方法具有较好的控制品质和鲁棒性。
In light of the characteristics of supercritical and ultra-supercritical main steam temperature control,such as multivariate,large time-delay and so on,based on planar fuzzy control,the method of compound fuzzy control is presented.This method overcomes internal disturbance,and integrates with the dynamic characteristics of fuzzy control.The simulation results show that compound fuzzy control performs better than serial PID control.
