多目标非线性控制分配方法研究

 提出了一种新的多目标非线性规划控制分配方法，对其理论基础、建模与求解过程进行了详尽描述, 并给出了多目标非线性控制分配的解的评价指标及评价方法。该方法不依赖于伪控制指令与广义操纵面偏转角度之间呈线性关系这一假设，直接处理非线性控制分配问题，并充分利用冗余操纵面，实现不同飞行条件和任务下对多种目标的综合权衡分配。仿真结果表明该方法具有较高的精度，能很好地处理故障情况下的控制分配问题，为控制重构提供了算法保证。

Research on Multi-object Nonlinear Control Allocation Method

A novel multi-object nonlinear control allocation method is brought forward in this article.The theory,modeling and problem solving of the method are presented in detail.The evaluation indexes and evaluation way of the multi-object nonlinear control allocation solution are described.The multi-object nonlinear control allocation method does not rely on the assumption that the produced pseudo-control commands,generally pitch,yaw and roll moments are linear relation with the generalized control effector deflections.The method can deal with the nonlinear relation between the produced moments and the control effector deflections directly.It can also make full use of the redundant control effectors to realize the integrated tradeoff multi-object control allocation under varying flight conditions and missions.The simulation results show that the control allocation method is effective and very satisfactory simulation accuracy is obtained.It can handle the control allocation problem under the circumstance of the aircraft effector fault and provide algorithm guarantee for reconfiguration.
