摘要: 本文用有限个时不变模型描述不确定多变量系统,给出了一种鲁棒控制器频域设计方 法,使得由控制器和任一模型构成的单位反馈系统都达到闭环的稳定性、渐近调节和跟踪、弱 相互耦合以及期望的瞬态特性.该方法应用于造纸机的多种纸张的定量和水份控制,获得了 令人满意的效果.Abstract: A multivariable system with significant uncertainty is considered and presumably characterized by p finite-dimensional linear time-invariant models. A robust controller is designed in the frequency domain such that the resulting feedback system satisfies all the given performance specifications for all models. It has been applied to the control of a papermachine.
