This paper extends this control technique to structures having several collocated sensor/actuator pairs. Conditions for the closed loop stability are derived, and the set of such stabilizing IRC controllers is shown to be a convex set. An experimental implementation of an IRC controller on an active structure (Cantilever beam) with two pairs of bonded collocated piezoelectric sensors/actuators is also presented.6en200810.1109/CDC.2008.473923062949225656
