为完善再入飞行复杂反推力器配置的控制性能分析,提出了新的分析方法.基于控制指令在空间分布的不均匀特性,提出了任务可行率指标,以获得任务可行的最佳完整配置组合;为有效判断控制指令扰动产生解突变的可能,引入矩阵条件数,提出了病态度指标;为反映配置矩阵抗羽流干扰的鲁棒性,基于最小奇异值理论提出了羽流抗扰度指标,并分别给出了各分析方法量化指标的具体实现.最后通过算例验证了该方法的有效性.
In order to improve the control performance analysis of the complex thrust reverser configuration of reentry flight, a new analysis method is proposed.According to the non-uniform distribution characteristics of control commands in space, a feasible index of the task is proposed to obtain the best complete configuration combination In order to effectively determine the possibility of solution mutation in the disturbance of control commands, the condition number of matrices is introduced and the disease index is proposed. In order to reflect the robustness of the anti-plume interference of the configuration matrix, the plume immunity index is proposed based on the minimum singular value theory , And gives the concrete realization of the quantification index of each analytical method.At last, the validity of this method is verified by an example.
