| 摘 要： | 提出了一种使用条件数来定量分析系统可观测性的新方法。该方法克服了传统可观测分析方法不能定量地分析系统可观测性的缺点,它不仅可以定量地时不变系统的可观测性,而且通过多量测估计和构建局部可观测矩阵的方法,还可以定量地分析时变系统在任意时间段内的可观测性能。同时给出了分析、计算实例。

| Abstract: | By using condition number, a new method to analyze quantificationally the observability of system has been discussed. It overcomes the disadvantage of traditional control theory observability method, which can not analyze observability of system quantificationally. It can not only analyze the observability of the time-invarying system quantificationally, but also by using multiple measurement estimation and building of local observability matrix, it can analyze quantificationally the observability of time-varying system in any time. And two typical examples are given to analyze and calculate. |
