摘要
该文提出在静态增益系数评价多变量控制耦合程度的基础上 ,增加动态耦合度和静态交叉耦合率二个概念 ,能更全面地评价多变量控制系统的耦合程度。对于 2× 2多变量控制系统 ,按系数正、负号的个数分为奇耦合和偶耦合 ,并证明奇耦合系统都能用解耦方法改善控制品质 ,同时给出解耦控制的计算方法。该方法可在电站控制系统得到广泛的应用。图 3参
In addition to static magnification coefficient, two new scientifically concepts were introduced in this paper to evaluate the coupling degree more precisely. A 2×2 multi variant control system can be classified as odd coupling system and seven coupling system according to the number of coefficient positive/minus sign. It was testified that any odd coupling system can be optimized by using de coupling method. The calculation method of de coupling was proposed in this paper and it can be applied extensively into power plant control system. Figs 3 and refs 6.
