The control of flexural vibrations in a stiffened beam using a piezoceramic actuator placed between the stiffener flange and the beam and a single error sensor is examined. A theoretical model is developed allowing for a variety of beam terminations. The effect of control source loca tion, error sensor location, frequency and stiffener flange length on the required control force and maximum achievable attenuation of acceleration level are discussed for beams with various types of terminations. Good agreement is obtained between experimental results and theoretical predictions.
