摘要

针对一类高阶非线性对象的降阶模型,给出了自适应控制律全局稳定的条件。在未建模的动态存在下。考虑到模型与实际的不同,调节特性保持在一个稳定区域。通过一组边界估计区域的大小,不仅证明了鲁棒性,而且还允许自适应和非自适应非线性控制之间的比较。

Adaptive Regulation of Nonlinear Systems with Unmodeled Dynamics
Conditions are given for global stability of an adaptive control law designed for the reduced order model of a class of higher order nonlinear plants. In the presence of unmodeled dynamics. which account for the difference between the model and the plant, the regulation property is preserved in a stability region. The size of the region is estimated via a set of bounds that not only proves robustness, but also allows a comparison between adaptive and nonadaptive nonlinear controls.
