| 中文摘要 |
| 利用Lyapunov函数方法克服“相空间”与“事件空间”之间的不一致, 以考虑时滞切换系统稳定性的分析与综合. 其一, 对将多Lyapunov函数方法推广至时滞情形, 由此给出子系统稳定性准则及切换序列的约束条件, 使整个系统是指数稳定的. 其二, 对于不稳定的时滞子系统, 提出了保证观测误差在任意切换作用下指数衰减的观测器设计方法, 并构造出基于估计状态的切换序列, 使状态变量指数收敛. |
| 英文摘要 |
| Lyapunov function approach is introduced to investigate the stability of switched systems with delay for overcoming the discordance between the “phase space”and “event space”, and yields results both in analysis and synthesis. Firstly, the multiple Lyapunov functions approach is generalized for the case of time-delay, from which the stability criterion of subsystems and the constraint condition on switching sequence are established for preserving the exponential stability of the switched system. Secondly, for the unstable subsystems with delay, the state-observer is designed to guarantee the exponential decay of the estimation error undergoing arbitrary switching action, and the switching law is also constructed from the estimated state to make state variables be exponentially convergent to zero. |
