将飞行器动力学模型中的质心运动和绕质心转动的运动分解开,并把这二部分有关的状态作适当处理,然后根据飞行试验数据,用分割辨识算法分别辨识飞行器动力学模型中的气动力和力矩系数。 仿真结果表明,这样处理既减少了程序工作量和计算时间,同时气动力和力矩系数仍有相当满意的辨识精度。
In the aircraft dynamics model, the centroid movement and the movement around the centroid are decomposed, and the relevant states of these two parts are properly dealt with. Then, based on the flight test data, the segmentation identification algorithm is used to separately identify the gas in the aircraft dynamics model Power and torque factor. The simulation results show that this method not only reduces the program workload and calculation time, but also the aerodynamic and moment coefficients still have quite satisfactory recognition accuracy.
