Embodiment 1
[0054] The method of the present invention is applied to the vibration control process of solar panels of spacecraft, assuming that the panels are composed of modular unit structures, ignoring the connecting parts between them, and considering that the panels are rigidly locked after deployment. The target structure size is 8.4m in length, 0.63m in width, 0.01m in thickness, and the structural damping ratio is set to 0.01. According to a limited number of sensors and actuators, the inherently consolidated solar panels are divided into multiple independently controllable smart component modules. Each smart component contains an actuator. force. The sensor and the actuator are arranged in the same position, and the measurement information is the displacement and speed change information of the corresponding position. In the simulation, the sailboard material is set as an aluminum plate with one end fixed and constrained, and the coordinate system used to build the model is give...
