Based On Dsp Navigation And Control Software Design And Implementation

Navigation and control software is the keys guidance and control task of precision strike weapons, is an software in a variety of technology integration. With the control system which is applicable to a air-to-ground missile as the background, this paper describes the design of missile control system hardware, and the principles of transfer alignment, navigation, guidance and attitude control . For the DSP features, these technologies to complete the integration of navigation and control software design models and implementation. The main content of this thesis:1. This paper introduces the principle of the missile control system and hardware environment, it is inseparable from the navigation and control software.2. Article describes the principles of transfer alignment, navigation, guidance and attitude control , the algorithm of these technologies will be directly reflected in the navigation and control software.3. For the characteristics of missile control system, this article describes the general design of the software, plans the entire structure and tasks of the navigation and control software.4.After designed the general design of the software, firstly, the paper describes the characteristics of DSP bootloader. With the analysis of bootloader, points out the shortcomings of common bootloader design, combines with the design of the memory partition, improves the bootloader's shortcomings ,which automatic load code is not enough and can not program FLASH. Secondly, the paper introduces the design process of the navigation and control software. Flow charts of chief parts of the software are presented. The article also describes the notes of design the navigation and control software by use of DSP platform. Especially in the communication interface , discussed the design of serial communication software, and selected the appropriate design to coordinate the work of the devices , by this way, improved the software efficiency and communication reliability.5. Tested the hardware system, and simulated and improved the software. In the end, made some experiments with guiding system, and made analysis on the experimental data.
