Constructive Nonlinear Control

递归局部最优设计是为了在期望运行状态的邻域内实现最优。这些设计保留了我们早期设计所保证的大区域稳定性和逆最优性。新的设计范式将包括交错的程序、内部钝化和具有生长限制的设计。这些新的发展将大大扩大我们的结果将适用的非线性系统的类别。未建模动力学和采样是反馈控制律实现中不可避免的问题。我们计划使用基于奇异摄动、无源性和小增益定理的结构特定工具来分析和增加非线性控制律对动态不确定性的鲁棒性。＊＊＊

These designs are to retain the large region stability and inverse optimality properties guaranteed by our earlier designs.New Design Paradigms will include interlaced procedures, internal passivation and designs with growth restrictions. These new developments will significantly enlarge the class of nonlinear systems to which our results will be applicable.Unmodeled Dynamics and Sampling are inevitable issues to be faced in the implementation of feedback control laws. We plan to analyze and increase robustness of nonlinear control laws to dynamic uncertainties using structure-specific tools based on singular perturbations, passivity and small gain theorems. ***
