梯格形自适应控制

Adaptive Control in Lattice and Ladder Form

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。为了考虑d步时延控制系统,采用简捷方法推导了d步梯格预报公式,并给出了控制量的确定方法。采用梯格形自适应控制可方便地调节模型的阶次,从而可以克服对象阶次不准引起的自适应控制失效的问题。

The problem of adaptive control of d step delayed multivariable system in lattice and ladder form is discussed and solved. The closed loop system under adaptive control is embedded into ARMA model, then using the algorithm of lattice and ladder form, the order and parameters can be predicted. A simple method can be used to derive the formulas of d step problems. The problem of unmodeled dynamics of adaptive systems can be overcome by using adaptive control in lattice and ladder form.
