研究了不确定系统的基于输入观测器的控制问题。描述了简单输入观测器的推广，该观测器以前已在几个汽车应用中使用，并与干扰消除控制器合并。所得到的控制方案具有半全局实用的闭环系统稳定性，即在适当的假设下，如果观测器的增益足够高，则它可以获得任意大的吸引域。此外，所提出的控制方案便于参考调节器的应用，以非保守地处理具有大扰动的约束系统。本文阐述了这种控制方案在飞机和航天器控制应用中的潜力。
The paper considers input observer based control of uncertain systems. A generalization of a simple input observer, that has been previously used in several automotive applications, is described and merged with a disturbance cancellation controller. The resulting control scheme enjoys semi-global practical closed-loop stability properties, i.e., under suitable assumptions it achieves an arbitrarily large domain of attraction if the observer gain is sufficiently high. In addition, the proposed control scheme facilitates the application of reference governors for non-conservative treatment of constrained systems with large disturbances. The paper illustrates the potential for use of such a control scheme for aircraft and spacecraft control applications.
