| Abstract: | The linear discrete-time fuzzy-state control system in the form of difference equations was studied.After transforming the fuzzy-state system into two families of crisp systems,the problem of observability was investigated with sufficient and necessary conditions.In accordance with the characteristics of the fuzzy-state systems,the concept of strong observability was further addressed,and the sufficient condition of strong observability was given afterwards.Meanwhile,some examples were shown to explain the theorems. |
