Stabilization Control for Strict-Feedback Nonlinear Systems With Time Delays
针对一类状态不可测且所有状态变量均含时变时滞的严格反馈非线性系统,提出了一种不依赖时滞的控制器设计方法,并证明了系统的渐近稳定性,最后通过化工反应器和张力腿平台仿真验证了有效性。
In this article, the output-feedback control problem for a class of nonlinear time-delay systems has been considered. Unmeasured system states and the time-varying delays which appear in all state variables bring great challenges to the controller design. Novel Lyapunov–Krasovkii functionals with control gains are proposed for a delay-independent controller. The system is proved to be asymptotically stable driven by the controller with suitable design parameters. Finally, we apply the new control scheme to a two-stage chemical reactor system and the time-delay tension leg platform system, the effectiveness of the control scheme is illustrated in the simulation results.
