In this paper, a finite-time output feedback control scheme is presented for a class of nonlinear systems in the p-normal form. The nonlinear functions in the systems are assumed to be bounded by both low-order and high-order nonlinearities multiplied by a polynomial-type output-dependent growth rate, which are able to cover a more general ones. A reduced-order observer is constructed to estimate unmeasurable states, and a finite-time output feedback controller is proposed for the considered system by constructing a new Lyapunov function and using the adding a power integration technique. Two simulation examples are given to verify the effectiveness of the proposed scheme.

基于输出反馈的一类 p 范式非线性系统的全局有限时间镇定

在本文中,针对一类p-正规形式的非线性系统,提出了一种有限时间输出反馈控制方案。假设系统中的非线性函数受低阶和高阶非线性约束,并乘以多项式型依赖于产出的增长率,这能够涵盖更一般的函数。构造降阶观测器来估计不可测状态,并通过构造新的李雅普诺夫函数并使用添加功率积分技术为所考虑的系统提出有限时间输出反馈控制器。给出了两个仿真例子来验证所提出方案的有效性。
