摘　　要：在锅炉燃烧系统中,汽包压力控制系统作为最重要的环节,针对系统具有非线性、多耦合、难以建立精确数学模型,因此采用传统的PID控制器,效果很不理想。为了提高系统的性能品质特性,提出将模糊控制理论和传统PID相结合,采用模糊自适应整定PID控制算法,对到蒸汽压力控制系统中进行仿真,结果表明具有超调量小、过渡时间短、稳定性好、适应性强等特点,达到了预期的控制效果,具有一定的工程参考价值。Boiler drum pressure control system has the characteristics such as non-linear,multi-coupling and uncertainty of mathematical model in the boiler combustion system.Traditional PID controller achieves the good results with difficulty.Based on the above situation,this article combined the fuzzy control theory and the traditional PID theory,and then proposed the fuzzy self-adjusted PID control algorithm.Adaptive turning of this algorithm is applied in the drum pressure control system to carry out the simulation research.The results show that this algorithm has small overshoot,short transition time,and good stability and adaptability.So this algorithm has achieved the desired control effect and is of value for engineering applications.
