A problem on the UAV navigation system based on multi-model variable structure intelligent control
XI Qing-biao · Journal of Xidian University · 2004
Due to the limit of traditional UAV navigation control, this paper puts forward a kind of navigation control system that is based on the strategy of multi-model variable structure intelligent control. If a discontinuous control structure is built up we can get good control quality by using a different control structure when the state of control system changes. At the same time not only is this system insensitive to the parameter perturbation but also this system can restrain wind disturbance. In a word, this system has strong robustness. Since it adopts the digital control method this system is easy to realize in engineering with high reliability.
