document: Resonant controllers for smart structures In this paper we propose a special type of colocated feedback controller for smart structures . The controller is a parallel combination of high-Q resonant circuits . Each of the resonant circuits is tuned to a pole -LRB- or the resonant frequency -RRB- of the smart structure . It is proven that the parallel combination of resonant controllers is stable with an infinite gain margin . Only one set of actuator-sensor can damp multiple resonant modes with the resonant controllers . Experimental results are presented to show the robustness of the proposed controller in damping multimode resonances
