In this paper, we consider a global regulation problem for a class of feedforward nonlinear systems. The key features of our considered system are identified by the presence of uncertain time‐varying parameters associated with main diagonal states and input and an unknown time‐varying delay in the input. Moreover, the growth rates of nonlinearity and the input‐delay are only known to be finite. To solve our considered problem, we give a process to obtain a compact set that contains the allowed time‐varying parameters. Then, we propose an adaptive controller which handles both unknown growth rate of nonlinearity and input‐delay for system regulation. We carry out the rigorous system analysis and show the effectiveness of our proposed control scheme via an application example.

输入时变参数不确定且时变未知的前馈非线性系统的自适应控制

在本文中，我们考虑了一类前馈非线性系统的全局调节问题。通过与主对角线状态和输入关联的不确定时变参数的存在以及输入中未知的时变延迟，可以确定我们所考虑系统的关键特征。而且，非线性和输入延迟的增长率仅是有限的。为了解决我们考虑的问题，我们给出了一个过程来获得包含允许的时变参数的紧凑集合。然后，我们提出了一种自适应控制器，该控制器可以处理未知的非线性增长率和系统控制的输入延迟。我们进行了严格的系统分析，并通过一个应用实例展示了我们提出的控制方案的有效性。
