摘要: 采用隐模型跟踪算法,针对多操纵面布局的飞机,进行控制增稳设计,要求具有满意的飞行品质.因而按照飞行品质规范和飞机动力学特性,对理想模型的选取做了深入分析;并对控制方案从指令跟踪精度、大气紊流响应和对其它扰动的抑制特性等方面进行了评估,其中用结构奇异值对增稳系统的鲁棒稳定性和鲁棒性能进行了分析.结果表明设计方案能有效抑制扰动,并具有合适的鲁棒稳定性和鲁棒性能.

Abstract: The implicit model following technique, based on linear quadratic theory, was applied to design the flight control augmentation system (FCAS) of an aircraft with multiple control surfaces. The selection philosophy for the ideal model was investigated, which is based on the flight dynamics and the flying qualities requirements. The closed-loop design schemes were evaluated according to command following accuracy and ability to subdue effects of the atmospheric turbulences and other disturbances, where the structured singular value analysis method was adopted to evaluate robust stability and robust performance of the FCAS. The results show that the designed FCAS can subdue the turbulence and has good robust stability and adequate robust performance.
