Stochastic discrete mathematical model of aerometric instrumentation control by data of flight recorders

Posted on by

UDC 629.7 BBK 39.56

Shomankov D. A.

The presented mathematical model is based on complexation and evaluation of heterogeneous flight parameters which are registered by data recorders or other concentrators that provide their post-flight processing by linear discrete Kalman filtering algorithms. The presented materials are based on previously obtained scientific results and are a continuation of the paper published in IIAJ «Crede Experto: transport, society, education, language» (2017, № 2, p. 115–125).

Key words: complexation, error estimation, control, controlled state, diagnostic sign, seminatural experiment.

Popov V. M.

The article presents a control algorithm for the servo drives of the gyro stabilized platform for unmanned aircraft vehicle (PUAV) for aerial photography and surveillance on the basis of the data from the 3-axis accelerometer and gyroscope located on the body of the UAV. The implementation of the algorithm using the servo SG90 with a programmable Arduino UNO hardware platform is reviewed.

Keywords: unmanned aircraft vehicle, gyro stabilized platform, micromechanical accelerometer, micromechanical gyroscope.
