Abstract :
Presents a method of controlling the first three vibration modes of a flexible structure using H-infinity optimal control. A feedback controller is designed based on the reduced order model and is capable of attenuating vibration without causing spillover instability. For this purpose, a three degree of freedom lumped parameter mass model of a plate structure is considered to control its vibrations using a dynamic output feedback controller and a static state feedback controller. The actuator dynamics and the placement of actuators are considered for an effective controller design method. The efficacy of both type of controllers is verified through experimental studies and compared
