State-feedback regulation for a class of higher-order nonlinear systems with integral input-to-state stability unmodeled dynamics
一类具有积分输入到状态稳定未建模动态的高阶非线性系统的状态反馈调节

We investigate the state-feedback regulation for a class of higher-order nonlinear systems with integral inputto-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.
