This paper considers the problem of ensuring the identifiability of the parameters of an uncertain linear system by means of feedback control. The problem is approached by considering time-varying controllers. It is shown that even when the uncertainty set is not finite, parameter identifiability can be generically ensured by switching among a finite number of linear time-invariant controllers. Practical aspects of the problem are also discussed in details.
