In this work, position and vibration control problem of a flexible robot arm with a voice coil type actuator is investigated. For the vibration suppression, a voice coil type actuator is designed and is implemented using H control scheme, in order to guarantee the controlled system robust against unmodeled higher-order mode vibration of the arm, output sensor noise, etc. A fuzzy logic based controller is used for the position and vibration control of the joint hub. Experimental results confirm that the proposed hybrid control scheme of combining fuzzy logic and H controller achieves efficient positioning and vibration suppression performances.
