Detectability of Nondeterministic Discrete Event Systems
The detectability problem is to determine or estimate the current and subsequent states of a system based on a sequence of observation when the initial state of the system is unknown. We assume that the system is nondeterministic in the sense that an event occurrence may lead the system to more than one state. The observation includes partial event observation and/or partial state observation. We defined four types of detectabilities: strong detectability, (weak)detectability, strong periodic detectability, and (weak)periodic detectability. Then we derived necessary and sufficient conditions for these detectabilities with and without state observations. Constructing an observer, which models the estimation of states under different observation,can check these conditions.
