Abstract
Air rudder is the actuating mechanism of the boost-glide aircraft, which is used to control the flight attitude of the aircraft. Before the flight test, the time domain and frequency domain identification should be carried out by measuring the performance indexes of the air rudder, which is used for the 6-DOF simulation of the aircraft. This paper designs the test platform and test scheme of the air rudder of the boost glide aircraft, and tests the performance of the air rudder. The time domain and frequency domain identification methods are used to identify the four air rudder models of the boost-glide aircraft in this paper, and the verification scheme of cross-comparison between the time domain identification model and the frequency domain identification model is proposed. The test results show that the time domain identification method has low precision and can only represent the steady-state response of the air rudder. The frequency domain identification method has high accuracy, which is suitable for characterizing the change process of the air rudder from the initial response to the stable state, and the identification results can be applied well in the attitude control system of the boost-glide aircraft.
