摘要
设计一种基于多面体不确定性的导弹鲁棒最优预见伺服地形跟踪控制器.在目标值已知的情况下,基于LQ/H∞准则,通过求解线性矩阵不等式(LMI),得到具有状态反馈、积分环节和预见环节的鲁棒控制器参数.仿真结果表明,这种鲁棒最优预见伺服控制器在具有良好地形跟踪特性的同时,比一般最优预见伺服方法具有更好的鲁棒性能.
A robust optimal preview servo terrain-following controller for a certain missile is designed based on polyhedron uncertainty. On condition that the object value were known and based on the guideline of LQ/H∞, The parameters of robust controller including the statefeedback, integration segment and preview segment gains could be obtained by solving the linear matrix inequality （LMI）. Simulation results show good terrain-following performance for this robust optimal preview servo controller. Moreover,the designed controller gives a better robust performance than a general optimal preview servo controller.
