Global State-Feedback Control for Switched Nonlinear Time-Delay Systems via Dynamic Gains

Abstract EN

In this paper, the problem of global state-feedback control is investigated for a class of switched nonlinear time-delay systems.

In order to obtain a less-conservative common dynamic gain update law across subsystems, we construct different dynamic gain update laws for individual subsystems.

Based on multiple Lyapunov function approach and adding one power integrator technique, the delay-independent controllers for all subsystems and a proper switching law are designed to guarantee that the states of the switched nonlinear time-delay systems can be globally asymptotically to the origin; meanwhile, all the signals of the closed-loop system are bounded.

Finally, an example is provided to demonstrate the effectiveness of the proposed method.
