Indoor Airships Modeling And Control Technology Research

In recent years, along with the development of modern material technology, computer technology, control technology and aviation technology unceasing development, no matter in military or civilian, airships autonomous control technology has received considerable attention. Because its unique flight performance and good cost-effectiveness ratio, airships become a kind of extremely development prospect of aircraft. What’s more, the indoor airships also has its own advantages, for example, they can be long time flights with very little power , and from the weather influences, which reduces control difficulty. These advantages make indoor airship have wider development space.According to the characteristics of indoor airship, the mathematical model of indoor airship is established, then its stability is analyzed, and based on this, the flight control law is established ,and through the simulation of MATLAB verifies the control effect. the concrete content as follows:1.The development history, the background and structure of indoor airship are introduced. A brief description is made about the airships research status both at home and abroad .The indoor airships extensive application value and good development prospect are summarized.2.Based on the Beijing science and technology museum special-shaped airships project, the mathematical model of indoor airships is established. The first problem of this paper is to utilize the existing theory and data to establish a mathematical model of indoor airship, and this model should facilitate undertake the controller design.3.According to the indoor airships motion equation, its stability is analyzed. First of all, the indoor airships matrix eigenvalues is analyzed, which can judge its stability. And according to the characteristics of qualitative change to an indoor airships characteristics of the movement modal, named its classification, and its physical cause.4.Then this paper studies the control rule of indoor airship. According to the linear decoupling after dissolve of two groups of multiple input multiple output state equation, the transfer function which is single input and single output is got. Finally through MATLAB SISO design tools get the control law.
