Software Design Of Guidance Aircraft Attitude Control System Based Upon Double DSP

With a variety of high-tech applications to aircraft guided weapons, the ability of all aspects of aircraft weapon has been greatly improved. The problem by using two chips on the aircraft control system software design as a flight control computer. Between two DSP chips for real-time communication via CAN bus, a DSP chip is responsible for data calculation, another DSP chip is responsible for steering gear control, that can further improve the control accuracy and response speed of the system.Paper first introduces the overall design of aircraft guidance control systems, after studying the aircraft control system theory, according to the overall hardware structure and function of the aircraft control system requirements, design Overall Software Solutions. By integrating the aircraft control system functional requirements, aircraft Control System is designed four major functional blocks, a detailed description of the software design process of each functional module. Combined with the subject in the practical application of the requirements, use Incremental PID control algorithm for processing the output signal and matlab/simulink control loop simulation, the simulation curve and the data to do a thorough analysis. In order to further improve the stability of the system, In the program to add the anti-jamming design software. In this paper, the software design in a modular way, using C programming language and assembly language programming mixed, the overall design of the aircraft control system software and four modules.Finally, the paper describes the aircraft control system each function module debugging process, a number of problems were analyzed, using the best solutions to the problems. The projects have been completed and the case of a brief summary, and the shortcomings of the proposed measures to improve the system.
