摘要
通过对CFB锅炉主汽温度动态特性的分析,针对主汽温度的大迟延、大惯性、慢时变及扰动因素多的特点,研究了模糊控制与PID控制相结合对主汽温度进行控制的策略。仿真研究表明,这种方案使控制系统具有较强的鲁棒性及良好的控制品质,提高了系统的动、静态性能指标。
Based on the analysis of dynamic characteristics of the main steam temperature, considering the feature of the large delay , the large lag and slow-time varying and the various disturbances for the main steam temperature, the centers around a strategy which combines fuzzy with PID control to control the main steam temperature . The simulation experiments show that the scheme provides a sounder control system as well as better control quality, thus improving its dynamic and static performance index.
