| 中文摘要 |
| 讨论了标准的周期黎卡提微分方程. 给出了其存在埃尔米特周期正定(HPPD)解的一个完整的充分必要条件. 准确地说, 在经过一个适当的状态空间基底变换后该条件通过能稳性和能检测性概念表述. 结果表明, 当HP PD解存在时, 它或者是唯一的, 或者有无限多个. 这一结果可以看作是Richardson和Kwong的结果对周期时变情况的扩展. |
| 英文摘要 |
| This paper deals with the standard periodic Riccati differential equation. A complete necessary and sufficient condition is presented for the existence of Hermitian periodic positive definite(HPPD) solution. Precisely, after a proper change of basis in the state space the condition can be expressed in terms of the notions of stabilizability and detectability. Moreover, it is shown that when an HPPD solution exists, it is either unique, or else there are uncountably many such solutions. The result of the paper can be considered as a valid extension of Richardson and Kwong's result to the periodic version. |
