Research on Maneuver Load Control Used to Fly-wing Aircrafts Based on Control Allocation

针对飞翼式飞机的非常规气动布局特点和传统的机动载荷控制方案存在的问题,将控制分配技术应用于机动载荷控制系统,得到了一种基于多操纵面优化分配的机动载荷控制方案.然后,采用分布估计算法以翼根弯矩为优化指标进行控制分配,实现了机动载荷控制,同时提供了一种翼根弯矩的估算方法,为优化算法的实施提供了便利。仿真结果验证了本方法的有效性。

For the unconventional layout feature of fly-wing aircrafts and questions of the traditional maneuver load control methods,control allocation technology was applied to the design of Maneuver load Control system,and the method based on multivariable optimization for control-surfaces allocation was proposed.Then,the estimation of distribution algorithm according to the optimization target of wing root bending moment was used for control allocation to implement maneuver load Control,also an estimation method of wing root bending moment was proposed providing convenience for this algorithm.Simulation results show the validity of the proposed approach.
