Abstract

With the recent introduction of spatially distributed piezoelectric transducers, distributed sensing and control of distributed parameter systems, i.e., elastic continua, can be realized in real physical systems. Since the transducers are spatially distributed in nature, sensor/actuator shapes are crucial to their spatial sensing and control characteristics. This paper is to present a new class of distributed line sensor/actuator specifically designed for sensing/control of shell symmetrical modes. Electromechanics of the line sensor/actuator is discussed and the membrane and bending contributions are analyzed. Sensing and control effectiveness of cylindrical shells are evaluated.
