针对具有结构不确定性的非线性系统，提出了一种新的控制李雅普诺夫函数的表征方法。在此基础上，研究了两类结构不确定性非线性系统的全局渐近镇定问题。分别得到了闭环系统全局渐近镇定的充分条件。另外，分别设计了状态反馈控制律，使闭环系统的平衡点全局渐近稳定。最后，通过仿真验证了该方法的有效性。
A new characterization of control Lyapunov functions is presented for non-linear systems with structural uncertainty. Based on this characterization, we deal with the problem of globally asymptotical stabilization of two classes of non-linear systems with structural uncertainty. Sufficient conditions for the globally asymptotical stabilization of the closed-loop system are acquired respectively. In addition, state feedback control laws are designed respectively to globally asymptotically stabilize the equilibrium of the closed-loop system. Finally, the simulations show the effectiveness of the method.
