Autonomous control technology is one of the three key technologies of unmanned airship, a lot of countries are launching research projects in this area, and have conducted some flight experiments; recently, our country also begins to launch some related research projects, but most of the work is just theoretic research and control law design's simulation, there are hardly any flight experiments of autonomous control technology.I have attended a project about unmanned airship which is one of the innovated projects of Chinese Academic of Science, and my focus is on the research of control system design, and our team has accomplished modeling unmanned airship, control law design, hardware system structure design of flight control system. Based on these achievements, I have been taking charge of software design of flight control system independently, which is the emphasis of the thesis.The beginning of the thesis is the introduction of the development histoty of stratosphere airship, especially the progress of modeling and control work; then it focuses on the control law design, including the discretization of the continuous system; after that, the thesis is about the construction of the platform of control system, including hardware platform and software platform, and the latter one is most in detail; The following part is the most important part of the thesis, it is about the software design, first is the overall design, including software framework, implemented thought and software flow, after that are the detail design of each child module; the last part of the thesis is the functional test of the software, and finally the performance of the software is proven.The software platform is Linux operation system, which makes the system of miniaturization, of effectiveness and low cost.The hierarchical control structure makes the system reliable, more portable and easy to realize.
