摘要
针对S1Tr近程空地导弹的特点，将导弹纵向运动的非线性模型通过参数雅克比线性化方法转化线性变参数（LinearParameter—varying，LPV）成LPV模型，基于IPV系统渐近稳定且具有H∞性能γ的充分条件，将控制器的设计转化为一组线性矩阵不等式的求解问题，并给出了LPV输出反馈控制器的构造方法。将LPV控制器在非线性系统上进行仿真，得出了比较满意的结果，验证了应用的有效性。
Based on the characteristics of STT Short-Range air-to-ground missile, the non-linear model of missile longitudinal motion was transformed to Linear Parameter-varying （LPV） model by parameter Jacobian linearization method. And, on basis of a sufficient condition of LPV system internally stable with a certain induced H∞ performance γ, the controller designing was transformed to a solving of linear matrix, and the construction method of LPV output feedback controller was put forwarded. The LPV controller designed was simulated in non-linear system with satisfying result and approving validity.
