Abstract
Since the supervisory control of fuzzy discrete event systems (fuzzy DESs) was established in 2005, there have been meaningful development. The main contributions of the paper include two points: First we establish another supervisory control theorem of fuzzy DES. Here our purpose is to achieve the objective set (specifications) \( \tilde{K} \) (instead of its prefix-closure language), and we use two supervisors to control the fuzzy DES, and \( \tilde{K} \) can be between the controlled languages generated by the two supervisors. Also, a test algorithm is described to check whether or not the fuzzy controllability condition holds. Second, we further show two fundamental properties of the largest fuzzy sublanguage and the s-mallest prefix-closed fuzzy controllable superlanguage of a given fuzzy language, and two equivalence characterizations of the largest fuzzy sublanguage and the smallest prefix-closed fuzzy controllable superlanguage are given.
