中文摘要
      研究了一类带有零动态不确定非线性系统有限时间镇定问题, 给出了具有更强实用性的停息时间可调的有限时间稳定控制设计方法. 基于有限时间稳定的Lyapunov理论和反推技术, 给出了停息时间可调有限时间稳定控制器的设计步骤. 所设计的状态反馈控制器使得闭环系统全局有限时间稳定, 且停息时间可调整, 特别是当系统初始值已知时, 停息时间可以任意调节. 仿真例子验证了本文的主要结论.
英文摘要
      The problem of finite-time stabilization is investigated for a class of uncertain nonlinear systems with zero dynamics, and the method is proposed to design the more applicable adjustable-settling-time finite-time stabilizing controller. Using the Lyapunov theory of finite-time stability and the backstepping methodology, the design procedure is presented for the adjustable-settling-time finite-time stabilizing controller. With the designed state-feedback controller in loop, the system is globally finite-time stable and the settling-time can be adjusted. Specially, when the initial conditions are known, the settling-time can be arbitrarily adjusted. Simulation results are given to illustrate the correctness of the main results.
