基于自适应逼近的控制通常使用具有一组预定义基函数的逼近器。最近的方法，空间相关方法，已经定义了自组织逼近器，其中当现有的基本元素被不充分激发时，新的局部支持的基本元素被结合进来。在本文中，将定义性能相关的自组织逼近器。设计者指定正跟踪误差标准。然后，基于自组织近似的控制器监视跟踪性能，并仅在需要时添加基本元素以达到跟踪规范。本文包括一个完整的稳定性分析。
Adaptive approximation based control typically uses approximators with a predefined set of basis functions. Recent methods, spatially dependent methods, have defined self-organizing approximators where new locally supported basis elements were incorporated when existing basis elements were insufficiently excited. In this article, performance dependent self-organizing approximators will be defined. The designer specifies positive tracking error criteria. The self-organizing approximation based controller then monitors the tracking performance and adds basis elements only as needed to achieve the tracking specification. The paper includes a complete stability analysis
