When Min-guided Bombs Aviation Flight Control Software Design And Implementation

This thesis is based on the engineering development of the aerial time-critical guided bomb simulation system as a background, in view of the guided bomb flight control system requirement, our team begins the design of guidance law、control law and flight control logic on embedded hardware platform and embedded real-time operating system DSP/BIOS, and in which DSP TMS320C6748is the core processor. And on this basis, I have been taking charge of the software design and software testing on flight control system independently by using hierarchical and modular construction. At last, semi-physical simulation experiment is studied to test and verify the validity and rationality of the software design according to the engineering development process.At first, the thesis comprehensively analyzes the whole structure of the aerial time-critical guided bomb flight control system, and the embedded computer platform is discussed in detail, which includes the core processor, hardware structure and communication interface.secondly, based on the analysis of the requirements for flight control system, the software overall design is accomplished. The software architecture of the flight control software is designed, and then it described the specific function and invocation of various modules in detail.In the third, according to the ballistic scheme of each flight phase, the thesis focuses on the independent software design of the attitude stabilization system of three channels, including pitching, yawing and rolling.The following part is the most important part of the thesis, it details the software design, first is the main program software flow chart, after that is the design process of each child module and the corresponding sub-function module flow charts.The functional tests of the software and the semi-physical simulation experiment of flight control system are the last part of the thesis, and the functional tests include communication function and the steering characteristics. Finally the performance of the software is proven in various initial conditions and complex environments.
