APPLICATION OF FLIGHT DATA RECORDER DATA FOR REMOTE PILOT MATHEMATICAL MODEL VERIFICATION
Keywords:automatic control system, data logging, flight controller, mathematical model, remote pilot, unmanned aerial vehicle
Objective: the various goals were set in the given research, such as: to carry out flights and perform standard maneuvers on different control modes; to gather flight data from unmanned aerial vehicle flight controller; to select the data according to the performed maneuvers in the corresponding flight control modes; to perform decoding of raw logged data for further analysis; and to prepare data for their substitution into the developed mathematical model at yaw control channel. Methods: experimental flights have been conducted according to a clearly defined flight mission for obtaining specific on-board records from the appropriate unmanned aerial vehicles control channels. Board data were analyzed and decoded. Comparison of the real values of angular velocity obtained during flight in rudder control channel under different control modes was conducted. Results: the initial data of the unmanned aerial vehicles turn performance in the manual and semiautomatic control modes were obtained taking into account the sensitivity scale factor. Based on the real values of angular velocities the angular velocity dependence on time was constructed taking into account the unmanned aerial vehicles control mode. Data obtained from rudder control channel, angular velocity, were converted from raw to real values and ready for verification of designed mathematical model. Discussion: it can be stated that remote pilot performs maneuvers more smoothly in the semiautomatic control mode since the self stabilization of the system is achieved through the influence on the part of automatic control system.
