We investigate the state-feedback regulation for a class of higher-order nonlinear systems with integral input-to-state stability(iISS) unmodeled dynamics. Based on the backstepping design technique and the properties of iISS, the design procedures for a state-feedback controller are developed by appropriately choosing the designed functions and the update laws of parameters. The designed controller guarantees that all the signals in the closed-loop system are bounded, and the states can be regulated asymptotically to zero. A simulation example demonstrates the effectiveness of the control scheme.%本文研究了一类具有积分输入到状态稳定(iISS)未建模动态的高阶非线性系统的状态反馈调节问题.基于反推技术和iISS的性质,通过恰当地选取设计函数和参数修正律,给出了一个状态反馈控制器的设计过程.设计的控制器保证了闭环系统所有信号的有界性,并且状态渐近调节到零.仿真例子验证了该控制方案的有效性.
