The use of a co-located piezoelectric, disk-shaped sensor/actuator is described for controlling several modes of vibration of an actual automobile fuel tank that is excited by a shaker. The shaker is attached to the tank where the fuel pump would normally be attached. Single mode control as well as multi-mode vibration control was achieved for both the empty as well as partially filled tank. The radiated noise caused by the structural vibration can also be controlled. Experimental results and short video presentation of the experiment will be made.
