Various problems have been investigated, especially those problems related to supervisory control =-=[1]-=-, [3], [8], such as controllability, observability, coobservability, and normality. However, there is one problem that has not been fully investigated. This is the problem of how to estimate or determ... |

State estimation problem is also studied in [7] and =-=[6]-=-. Our work is different from [7] and [6] because we investigate the state estimation problem from all possible angles which includes the results of [7] and [6] as special cases. In particular, we defi... |

State estimation is first studied using automata in an abstract sense in =-=[12]-=- and the idea is followed by many others, including us. In that sense, our note can be viewed as an extension of the work presented in [12]. However, our note is more specific and investigates state e... |
