摘要
针对飞机在高空高速下阻尼不足以及稳定性较差的问题,用最优二次型的隐模型跟踪方法设计控制律,改善其纵向操稳特性,从而提高飞行品质。通过对系统进行动态仿真,对比加入控制律前后飞机的动态响应结果,验证了此设计方法的有效性。
For the underdamped and the defective-stable in high-altitude and high-speed about plane,the design process about implicit model tracking of linear-quadratic-optimal-controller was discussed,the design improved the longitudinal stability characteristics of operation and flight quality.By systematic dynamic simulation,compared the dynamic response with and without control law,the control law was proved effective.
