The invention relates to a piezoelectric active vibration damping device for a flexible solar wing supporting structure. The piezoelectric active vibration damping device comprises the flexible solarwing supporting structure and a control module. The flexible solar wing supporting structure includes a solar wing pedestal and a flexible solar wing supporting structure body, the flexible solar wingsupporting structure body comprises a plurality of short supporting rods and two long supporting rods which are flexible and capable of being curled, and the two long supporting rods are installed onthe solar wing pedestal separately and connected with each other through the short supporting rods. The control module comprises a controller, an acceleration sensor, piezoelectric sensors and piezoelectric actuators, the controller is arranged on the solar wing pedestal, the acceleration sensor is installed on one short supporting rod, each long supporting rod is provided with one piezoelectricactuator and one piezoelectric sensor, and the acceleration sensor, the piezoelectric sensors and the piezoelectric actuators are all electrically connected with an external power supply through the controller. The piezoelectric active vibration damping device is reasonable in design and can effectively solve the problem of vibration of flexible solar wings.
