滑翔式飞行器姿态控制系统跟踪性能评估

Clearance of tracking performance of flight control systems for gliding vehicles

针对飞行控制系统性能评估的要求,提出了鲁棒跟踪性能准则.给出了两种适用于该准则的分析方法:线性矩阵不等式方法,组合优化方法.线性矩阵不等式方法采用自适应分块策略,将参数空间分割成多个小块,并单独判断各个块的跟踪性能;组合优化方法结合序列二次规划和差分进化算法,直接在参数空间内搜索最大的满足准则要求的超立方体.以BTT导弹的俯仰通道姿态控制为例,对两种方法的使用进行说明,并通过仿真对评估结果进行了验证.

The requirements of flight control system clearance was analyzed, and a robust tracking performance criterion was introduced. Then two analysis approaches to this criterion were proposed： the LMI（linear matrix inequality）-based approach and the hybrid optimization one. An adaptive box- dividing strategy was used to split the parametric space into a lot of little boxes, and the tracking performance of each box was analyzed. The latter approach, which combines sequential quadratic programming and difference evolution algorithm, directly searches the biggest super-cube that satisfies the requirement in the parametric space. At last, two approaches were both illustrated via an example of the pitch attitude control system of BTT （back-to-turn） missile, and the clearance results were validated by simulation.
