Internal control recovery on Klein-Gordon systems. (English) Zbl 1107.35380
Summary: We report some results on a method, to recover internal input applied to Klein-Gordon systems with a time-varying parameter if we know the output and the initial data only partially. To determine the internal input, the method, called the sentinel method, uses the information from a certain functional acting on some part of the boundary.
