Flight-by-wire control strategy: An implementation of stepping simulation approach

Flight control system is extremely important for the aircraft flight safety and quality. With the rapid and continual development in modern aeronautical fields, fly-by-wire control (FBW)system has become the leading of aircraft design and application. In this paper, aim at the need of the certain cargo-transport, the modeling and simulation as well as the parametric-optimization of flight control system are systematically discussed, based on MATLAB/Simulink. The mechanical model of the flight control system is presented, and a suit of flight control law is proposed. The model of flight control system is set forth in MATLAB/Simulink based on the control law, the real-time simulation of control system, the analysis of planepsilas dynamic response characteristics, and the modification and optimization of the system parameters are implemented. The FBW system is analyzed by stepping simulation, and the effects on the dynamic character of the whole systempsilas response due to each block is studied.
