| Abstract | In this paper, we present two strategies to stabilize the altitude of the towed body (drogue) in the presence of the steady wind. The ight test results are presented to verify the concept of aerial recovery and the mathematical model of the system. By using the parameter con guration and the data collected in the ight test, a matching work is conducted to testify the delity of the mathematical model in the simulation. A series of trade studies are developed in the simulation to analyze the design parameters. In the presence of the steady wind, two proportional-integral controllers are developed to stabilize the altitude of the drogue. The simulation results illustrate the feasibility of the two methods. We also develop an Extended Kalman Filter (EKF) to estimate the drogue states in the case of data delay and the simulation results are presented. |
