A Solution for Aircraft Control Allocation

针对现代飞控系统中的控制分配问题,提出了一种基于经典理论的最优化方法——有效集方法的控制分配方案,并建立了该方案的两种算法实现;简要描述了具有多个操纵面,考虑位置和速率约束的飞行控制中的控制分配问题,并将其转化为约束二次型规划问题进行研究;讨论了现有的几种控制分配解决方案;最后,以某型飞机为仿真模型,对新的和以前的几种控制分配方案的算法实现进行了对比仿真验证。仿真结果和数据统计表明,提出的这种基于有效集方法的控制分配解决方案对于实时飞行控制分配问题是切实可行且高效的。

As a classical optimization, the active set method is investigated and two algorithms based on active set method are developed and implemented in aircraft control allocation, which is often transformed into constrained quadratic programming problem. Here, basic aircraft control allocation is described and formulated simply, and several methods for solving the control allocation are discussed. In addition to the two posed algorithms, several previous algorithms are also implemented for comparison. Performance and computational feasibility is evaluated using aircraft model with many more actuators, which suffering from position and rate constrains. Results by simulation show that this control allocation method is feasible, effective and successful.
