摘要: 本文讨论并解决了具有d步时延的多变量系统的梯格形自适应控制问题.为此,把自适 应控制下的闭环系统嵌入到ARMA模型中,采用梯格算法进行预报;用简捷方法推导了d步 梯格预报公式,并给出了控制量的确定方法.采用梯格自适应控制可方便地调节模型阶次,从 而可以克服对象阶次不准引起的自适应控制失效问题.Abstract: The problem of adaptive control of the d-step delayed multivariable systems in lattice and ladder form is discussed and solved. The closed-loop system under adaptive control is embeded into the ARMA model. Then the algorithm of lattice and ladder form is used to predict the order and parameters. A simple method is adopted to derive the formulas of the d-step problem. The problem of unmodeled dynamics in adaptive systems can be solved by using adaptive control in lattice and ladder form.
