A standard bridge between automata theory and logic is provided by the notion of
characteristic formula. This paper investigates this problem for the class of
event-recording automata (ERA), a subclass of timed automata in which clocks are
associated with actions and that enjoys very good closure properties. We first study the
problem of expressing characteristic formulae for ERA in Event-Recording Logic (ERL ), a
logic introduced by Sorea to express event-based timed specifications. We…

The specification and the controller synthesis problem for real-time systems are considered and it is shown that the satisfiability of C-WTmu is decidable, which means that every formula is equivalent to a formula in disjunctive normal form.
