针对现代飞行器操纵面个数多且控制效率相互耦合,难于直接构建虚拟控制指令可达集的问题,在研究控制分配技术的基础上提出了一种通用的构建方案。基于线性控制分配模型,分别对独立操纵面和共面操纵面两种情形分析了虚拟控制指令可达集的基本性质。通过向量的空间运算获取了可达集的边界顶点,结合凸包络理论构建了可达集的几何外形,给出了其体积的计算方法。仿真实验表明,该方案不受操纵面个数的限制,能够快速准确地构建所有操纵面组合的虚拟控制可达集,对其他过驱动系统都是可行的。
In view of the large number of control surfaces of modern aircraft and the coupling of control efficiency, it is difficult to directly construct the reachable set of virtual control instructions. Based on the research of control distribution technology, a general construction scheme is proposed. Based on the linear control distribution model, the basic properties of reachable set of virtual control instructions are analyzed respectively for two independent control surfaces and coplanar control surfaces. The vertices of the reachable set are obtained by the vector operations. The geometric shape of the reachable set is constructed based on the convex envelope theory. The calculation method of the volume is given. The simulation results show that this scheme is not limited by the number of control surfaces and can construct the virtual control reachable set of all control surfaces quickly and accurately, which is feasible for other overdrive systems.
