The impact of sensor positions on aerodynamic parameter identification

Abstract In this paper, a 3211 excitation simulation is performed on the longitudinal aerodynamic model of the F16 aircraft, and the simulation data collected at the sensor and the data collected at the center of gravity are obtained respectively. Although the difference between the two sets of data is small, by the comparison of the aerodynamic parameters identified from the two sets of simulation data and the truth value of the aerodynamic parameters, it is found that the identification result of the data at the center of gravity is better than the data at the sensor, which indicates that position correction of the sensor is one of the key steps in the system identification data processing.
