摘要
以建立的质量矩拦截弹数学模型为基础,通过对模型合理简化,得到一个耦合的非线性动力学系统。利用微分几何的反馈线性化理论,得到一个解耦线性系统。考虑到拦截弹的鲁棒性要求和三个滑块的协调控制问题,提出基于误差的积分准则(ITAE准则),考虑混合灵敏度S/T问题,采用H∞控制理论对拦截弹进行姿态控制系统设计,仿真结果验证了这种方法的有效性。
Based on the constructed model of mass moment interception missiles （MMIM）, a coupled nonlinear system is presented by rational simplification. A decoupled linear system is presented by using feedback linearization approach of the differential geometry theory. To meet the demands of the robustness of interception missiles and the coordination of the three masses control, on the basis of integral of time-weighted absolute error criterion （ITAE criterion）, the attitude control system of interception missiles is designed by considering the mixed-sensitivity S/T problem of H control theory. The simulation results illustrate the efficiency of this method.
