导航系统多模变结构智能控制研究

A problem on the UAV navigation system based on multi-model variable structure intelligent control

针对传统无人机导航控制的局限性,提出基于多模变结构智能控制策略的导航控制系统.在飞行导航控制系统内建立不连续控制结构,当系统状态发生变化时,启用不同控制结构以获得优良的控制品质,同时系统具有较强的对系统参数摄动不敏感性以及风场扰动抑制能力,系统鲁棒性强.采用数字控制技术,系统工程实现简单且可靠性高.

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.
