Active vibration control of axisymmetric membrane through partial pole placement

This paper deals with the problem of active vibration control for a flexible axisymmetric membrane. mechanical system is equipped two piezoelectric circular chips where one them works as an actuator, whereas other used sensor. Both are glued on membrane, each side, and centered according to its axis symmetry. The model this obtained from finite element modelling, leading linear state-space model. design proposed controller based delayed proportional actions. We exploit property called Coexisting Real Roots inducing Dominancy assignment spectral values in appropriate sector corresponding desired damping. aim work examine performances output feedback terms damping main observable controllable vibrating modes.
