Sampled-Data Delayed Output Feedback Control of a Class of Nonlinear Systems
Xiaoru Niu, Wei Lin
Abstract
This letter presents a sampled-data control strategy for robust stabilization of a family of uncertain nonlinear systems via delayed output signals. Instead of building dynamic observers,we use an output signal sampled at the current time and delayed outputmeasurements at the previous n -1 sampling points to design sampleddata controllers, which are easier for implementation by computer. Under a linear growth condition, it is proved that global robust stabilization is achievable by sampleddata delayed output feedback. The robust stability analysis of the hybrid closed-loop system with delays is conducted by the Lyapunov-Krasovskii functional method.
