In order to improve the vibration suppression ability of the flexible structure of the new sensor, it is necessary to carry out the vibration optimization control design of the flexible structure, and a new vibration optimization control method of the flexible structure of the sensor based on telemetry technology is proposed. The vibration dynamic model of the flexible structure of the new sensor is constructed, and the vibration dynamics and kinematic model of the flexible structure of the new sensor are constructed under the velocity coordinate system and the volume coordinate system. The Kalman filter method is used to realize the fusion adjustment and small disturbance suppression of the vibration parameters of the flexible structure of the new sensor. The vibration modal parameters of the flexible structure of the new sensor are identified by the Aeroelastic modal parameter identification method, the vibration characteristics of the flexible structure of the new sensor are extracted, the inertial parameters of the vibration of the flexible structure of the new sensor are identified by telemetry technology, and the stability control is carried out by combining the state feedback adjustment method to realize the optimal vibration control of the flexible structure of the new sensor. The simulation results show that the proposed method has good adaptability and robustness, and has good vibration suppression and control ability.
