This paper describes two feedback control systems of active modular panel systems for insulating floor impact noise. The feedback control system is constructed with five sensors of the vibration acceleration, five actuators of the electro-magnetic type and the digital controller, which means MIMO control system basically. In order to decrease the computing load of the controller, the technique of decoupling the natural modes of vibration in the panel is applied. Individual controller is constructed for each decoupled natural mode. We investigate a suitable controller for the micro computer by comparing with control results of two control systems: robust feedback and output feedback.
