Abstract
The article is an independent work containing the author’s ingenious research methodology and the model of the control system of Unmanned Aerial Vehicles. Furthermore a unique and world first mathematical model of an Unmanned Aerial Vehicle was developed, as well as a simulation program which enabled to investigate the control system of any Unmanned Aerial Vehicles in the tilt duct pitch (altitude), bank (direction), deviation and velocity, depending upon the variable values of the steering coefficient, reinforcement coefficient and the derivative constant. The research program was written in the language of the C++ as the MFC class, on the MS Visual Studio 2010 platform. The main issue resolved in the article is the pioneering research of the process of control during manual and semi-automatic guidance of the Unmanned Aerial Vehicle, with a jet propulsion system to the coordinates of preset points of the flight route. Modelling of the flight control system takes into account: the logical network of operations of the simulation program, the pilot-operator model, the set motion and control deviations as well as the flight control laws. In addition, modeling of the control system takes into account the drive model, engine dynamics, engine thrust, the model of steering actuators and the model of external loads. In contrast, the external load model takes into account the external forces acting on the unmanned aircraft, including gravitational forces and moments, aerodynamic forces and moments, aerodynamic drag, aerodynamic lateral forces, aerodynamic lift forces, aerodynamic heeling moment, mechanism of local angle of attack from damping torque and forces and moments from the engine.
Highlights
The importance of unmanned aerial vehicles has clearly increased in the last decade
They do not have on board equipment necessary to secure and support the life of a human pilot, from the point of view of control, navigation, communication, visualization, control, diagnosis of the current technical condition, situational awareness and own safety during the mission, there are much more complicated than manned aviation
The scientific and utilitarian aim of the above-mentioned work was a systemic approach to the problem of modelling and testing the control process of Unmanned Aerial Vehicles in the manual control mode and the semiautomatic mode
Summary
The importance of unmanned aerial vehicles has clearly increased in the last decade. They are irreplaceable during long-term, dangerous tasks and conducted in an adverse environment without endangering human life. The scientific and utilitarian aim of the above-mentioned work was a systemic approach to the problem of modelling and testing the control process of Unmanned Aerial Vehicles in the manual control mode and the semiautomatic mode. Another goal was to develop a research methodology, a model of flight control system, modeling of unmanned aircraft as a control object and the results of simulation tests of unmanned aircraft. The system is sensitive to the assumed proportional and integrating element parameters that determine the ship’s steerability and stability
