| 中文摘要 |
| 研究了一类含有未知参数的非线性系统的半全局实用镇定问题,通过系统线性部分和零动态部分的Lyapunov函数构造了整个系统的Lyapunov函数,据此设计了使系统半全局实用稳定的状态反馈和动态输出反馈,且证明了只要未知参数不改变系统的相对阶,那么控制器是鲁棒的.仿真实例说明了所提出方法的有效性. |
| 英文摘要 |
| The semiglobally practical stabilization of a class of nonlinear systems with unknown parameters is considered.A Lyapunov function for the overall system is established through a Lyapunov function of the linear part and that of the zero dynamics.A state feedback and a dynamic output feedback are designed respectively to stabilize the system.It also verifies that the controllers are robust as long as the variation of unknown parameters maintains the same relative degree.A simulation (example) shows its effectiveness. |
