Heck, L., Olkin, J.A., & Naghshineh, K. (1998). Transducer Placement for Broadband Active Vibration Control Using a Novel Multidimensional QR Factorization. Journal of Vibration and Acoustics, 120, 663-670.
This paper advances the state of the art in the selection of minimal configurations of sensors and actuators for active vibration control with smart structures. The method extends previous transducer selection work by (1) presenting a unified treatment of the selection and placement of large numbers of both sensors and actuators in a smart structure, (2) developing computationally efficient techniques to select the best sensor-actuator pairs for multiple unknown force disturbances exciting the structure, (3) selecting the best sensors and actuators over multiple frequencies , and (4) providing bounds on the performance of the transducer selection algorithms.
