Abstract研究了变质心弹头对配平攻角的能达性条件。针对气动力矩小于滑块惯性力矩的控制失稳问题,利用内模原理,通过增加滑块动力学观测器,将滑块状态引入并结合逆解耦机制,达到去惯性力矩化的局部姿态角速度反馈条件,使用自适应PD控制实现弱气动环境下的变质心稳定控制。仿真结果验证了该方法的有效性。
Other AbstractThe reachability qualification to trim AOA by moving mass method was analyzed.For the unstable problem of mass moment control when aerodynamic moment is less than the inertia slide moment,partial attitude angular speed feedback condition without inertia moment was achieved by using internal model principle and slide dynamic observers and unifying inverse decoupling mechanism.Stable control of moving mass under weak aerodynamic environment was realized by using self-adaptable PD controller.Simulation results verify the validity of the method.
