Abstract :
Traditional methods for testing the controllability of a system often do not provide satisfactory answers, since a system can be controllable, but in fact be "very close" to being uncontrollable, i.e., a controllability measure based on a continuous metric rather than a discrete metric is highly desirable. In this paper a simple and computationally efficient formula is presented for the calculation of the real controllability radius
