【摘要】 针对简易制导航弹非线性模型,运用微分几何理论和现代控制思想,提出了一种分层控制方法,即将该模型分为质心层、速度层、姿态层和角速度层,使其具有仿射型特点,然后根据各层间的关系进行控制器设计.仿真结果表明,这种分层控制器较传统控制器具有更好控制品质,且实现简单,同时满足简易制导航弹低成本要求.更多还原

【Abstract】 The nonlinear dynamic model of a guided bomb can be dealt with a nonlinear time variable system based on the differential geometry and advanced control theory, which is separated four layers: centroid, velocity, attitude, angular rate. A novel nonlinear hierarchical controller is designed through an affine model based on the four layers. The simulation shows this controller makes the duided bomb acquire a good flying quality. Moreover, such a design is of lower cost for leaving out the measure devices of attitude. At the same time, the controller has improved the control accuracy of the guided bomb and ensures the bomb’s stability.更多还原
