Photostrictive actuator, which can induce control actions under irradiation of high-energy lights, has been investigated for non-contact active vibration control of flexible structures in the last decade. A number of photostrictive actuator configurations with uniform control actions have been designed and evaluated. In this study, boundary conditions of a quad-photostrictive actuator design are altered so as to achieve continuous non-uniform control forces and control moments. Distribution of the actuator induced strains are defined by the variation method. A new skew-quad photostrictive actuator design which can induce multidegree of non-uniform control forces and moments is proposed. Photonic control of a simply supported cylindrical shell laminated with this skew-quad actuator is investigated. Control actions of center-located skewquad actuator are defined in the modal domain. Control actions with different surface coverage or actuator sizes are evaluated.
