摘要 微型飞行器动力学特性分析是MAV设计中的一个重要环节.本文以某型飞翼式MAV为研究对象,根据改进的线性化模型对MAV纵向和横侧向整个飞行范围内的动力特性进行分析.分析表明,所研究的MAV在整个飞行范围内其纵向运动特性差异明显,横侧向螺旋模态不稳定,而荷兰滚模态稳定且具有较大的阻尼比.本文的研究工作对飞翼式MAV控制系统的成功研制具有重要的指导意义. Stability Analysis of Micro Air Vehicles（MAV） plays an important role in MAV design.To a certain type of flying-wing MAV for the study,the dynamic characteristics of MAV were explored under the conditions of various speeds based on a novel version of linear-time-invariant（LTI） model.The results showed that the MAV＇s longitudinal dynamic characteristics are very distinct in different speed.The spiral mode is un-stability,but dutch-rolll mode is stability and has good damping ratio for lateral motion.The present analysis is useful for flight control design of MAV.
