This paper describes the 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, and 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 decoupling technique of the natural modes of vibration in the panel is applied. An individual SISO controller is constructed for each of decoupled natural modes. Each mode is controlled simultaneously by parallel driver for each controller. We show effectiveness of the proposed control methods with the results of experiment, and now we develop a suitable controller with the micro computer comparing computing loads between MIMO control system and SISO parallel control system.
