Abstract：Photostrictive materials, like ferroelectric lanthanum-modified lead zirconate titanate (PLZT) ceramics, can produce a photodeformation effect under irradiation of high-energy lights and thus can be employed in non-contact actuation and control of flexible structures. Based on couplings of opto-piezo-thermoelastic fields, mathematical modeling of the photostrictive actuator is presented. Governing equations of the cylindrical shell laminated photostrictive actuators are formulated. The control effectiveness of distributed actuators with two configurations is evaluated with the control actions. Based on the configuration of the actuators, the bending effect and membrane effect are analyzed while the curvature angels of the cylindrical shell are changing. Finally, the Lyapunov and proportional velocity feedback control algorithms are studied and the simulation results show that the distributed actuators are effective to controlling the low-frequency oscillations of thin cylindrical shells.
