Abstract:
In this article, the simulation and integrated control of flight-propulsion are addressed as a significant and necessary research topic in the aerospace industry. In previous research, flight control and turbine engine control have often been treated separately; however, the mutual effects of flight dynamics and turbine engine dynamics on one another have received less attention. Initially, to model the movement of the UAV body, kinematic and flight dynamics equations are presented. Transmission equations are developed based on Newton’s laws, and rotational equations are derived from Euler’s theory. Subsequently, the thermodynamic and dynamic equations necessary for turbojet engine modeling are introduced. The equations governing the engine inlet opening, compressor, turbine, combustion chamber, and nozzle are examined separately. All simulations are conducted in MATLAB/Simulink. Flight graphic is displayed in real-time using FlightGear software. A structure for simulating and controlling flight dynamics and engine dynamics is proposed, addressing not only the control of flight and the UAV’s trajectory but also the control of the shaft’s rotational speed while observing the limitations of the turbojet engine. Additionally, flight-propulsion control coefficients are simultaneously optimized for a specific mission using genetic algorithm. Finally, the simulation results are presented and discussed.
