“…They couple the equations of motion of the real modes and they can affect the stability of the controlled system and the performance itself. Equation (17) gives the first analytical relationship between spillover effects for IMSC and the positions of sensors and actuators on the flexible structure.…”

“…A few works [9,16,17] have studied the dependence of spillover effects on the mutual positions of actuators and sensors when IMSC is applied. However, these studies are based on very complex mathematical approaches which cannot easily be applied within ordinary engineering practice.…”

“…A trade-off between these two approaches can be foundin [8]and[26]. Unfortunately, although these approaches can reduce observation spillover, control spillover still remains.A few works [9,16,17] have studied the dependence of spillover effects on the mutual positions of actuators and sensors when IMSC is applied.

“…From equation (17) it can be noted that, even assuming the gain matrix r ⎡ ⎣ ⎤ ⎦ as diagonal, the system is characterized by a total damping matrix that is no longer diagonal. The extradiagonal terms r i j , and r j i , (generally non null) can be considered as representative of spillover effects.…”

structure [3]. However, these limits could be considered less burdensome if new technologies, such as optical strain gauges [6-8], are adopted.A variety of modal control algorithms has been specifically developed for civil engineering structures [10,11], and mechanical [5] and aerospace systems [15,18]. How-ever, the great potential of the independent modal space control (IMSC) technique has not been fully exploited yet, mainly because of problems related to spillover effects. A few works have suggested containing spillover effects by using modal filters on measurements. This can be achieved by using filters on signals [3,21,25]orusingmodalsensors [23,24]. A trade-off between these two approaches can be foundin [8]and[26].
