Mathematical Modeling and Simulation of a Twin-Engine Aircraft Fuel System Using MATLAB-Simulink

摘要

Engineering applications of control systems has been in the forefront of technological advancement and development of mechanically automated machines as well as complex interconnected systems. In the aerospace industry, the adoption and integration of control system for fuel system of an aircraft which is a complex series of interconnected devices such as pumps, valves, injectors, switches, metering and monitoring devices that are required to supply fuel in proportion for effective and efficient engine’s throughput. This analysis is involved with fuel depletion rate of a model flight cycle considering all the aircraft static and dynamic variables. A theoretical model is sampled and tuned with a Proportional Integral and Derivative (PID) controller to interface a light-wing two-engine aircraft fuel system in order to control the fuel flow, monitor and optimize efficiency within the fuel system. A mathematical model is developed for the fuel system and simulated on MATLAB-Simulink software. The fuel consumption profile is plotted and the extracted results validated with similar analogous plots by Robert and Vladmir.
