Abstract：Based on experimental observation and theoretical analysis, constitutive equations which define the time history response of photo-induced strain for 0-3 polarized PLZT actuator are presented. The relationships of saturated photovoltage and time constant with actuator thickness and light intensity are formulated. Active vibration control of open cylindrical shell by non-uniform actuation induced by a new skew-quad phtostrictive actuator system is investigated. Considering the actuation behavior of photostrictive actuator, the velocity feedback half-cycle control scheme with constant light intensity is adopted. The simulations indicate that the vibration of cylindrical shell can be effectively controlled by this control scheme. Compared with 0-1 polarized PLZT actuator, 0-3 polarized PLZT actuator can get better control effectiveness of the cylindrical shell due to its higher response speed, and the control effectiveness can be improved by increasing the light intensity.
