针对一类同时具有参数不确定性和未知非线性的非线性系统，提出了一种自适应控制设计方法。未知的非线性位于一些“边界函数”，这是假定为部分已知。关键的假设是不确定项满足“三角条件”。“如实例所示，所提出的设计过程扩展了可应用全局自适应镇定方法的非线性系统的类别。整体自适应计划，以保证全球一致的最终有界性。
An adaptive control design procedure for a class of nonlinear systems with both parametric uncertainty and unknown nonlinearities is presented. The unknown nonlinearities lie within some "bounding functions" which are assumed to be partially known. The key assumption is that the uncertain terms satisfy a "triangularity condition." As illustrated by examples, the proposed design procedure expands the class of nonlinear systems for which global adaptive stabilization methods can be applied. The overall adaptive scheme is shown to guarantee global uniform ultimate boundedness.
