Aircraft guidance and control integrated design method based on preset performance

The invention discloses an aircraft guidance and control integrated design method based on preset performance, relates to the technical field of aircraft guidance and control, and aims to solve the problem that in the prior art, a traditional aircraft modeling method only considering single matching disturbance is difficult to meet the requirement of a high-precision control task. The method is oriented to a hypersonic flight vehicle guidance and control integrated mathematical model containing matching/non-matching disturbance, an extended state observer is designed based on a preset time thought, and meanwhile, the design of an integrated controller meeting performance constraints is realized by combining a preset performance thought and a backstepping sliding mode control theory. According to the invention, the requirement of high-precision control tasks can be met. 一种基于预设性能的飞行器制导控制一体化设计方法，涉及飞行器制导控制技术领域，针对现有技术中仅考虑单一匹配扰动的传统飞行器建模方法难以满足高精度控制任务的需求的问题，本申请面向含匹配/非匹配扰动的高超声速飞行器制导控制一体化数学模型，基于预设时间思想，进行扩张状态观测器的设计，同时结合
