基于状态空间方程的多变量pid-mac在锅炉燃烧控制系统中的应用
, PP. 48-53
Keywords: 锅炉,燃烧系统,控制,状态空间方程,多变量,pid-mac算法
Abstract:
为了克服锅炉燃烧系统多变量、强耦合、强干扰、大滞后的特性,提出了基于状态空间方程的模型预测算法控制(mac)与pid控制相结合的新型多变量pid-mac算法,并采用李雅普诺夫第二方法证明该算法导出的控制律可使控制系统闭环、稳定。以燃气锅炉燃烧系统为对象,通过仿真试验证明了该算法不仅具有pid控制稳态误差小、上升时间短以及超调小的优点,而且在一定程度上克服了pid控制调节时间长和模型算法控制稳态误差较大的不足。
