Abstract
Hybrid control systems can arise when a discrete
event system is used to supervise the behaviour of
continuous-state systems. In this context, tlie DES
supervisor manipulates syiiibols which are represen-
tative of events occuring within the plant's state
space. An important issue in the design of such con-
trol systems concerns conditions under which such
symbolic manipulations are sufficient to adequately
supervise the plant. This paper provides a method for
identifying such supervisable events whose computa-
tional complexity is polynomial in plant complexity.
