摘要
针对倾斜转弯(BTT)飞行器姿态控制系统的多变量耦合问题,提出一种基于扩张状态观测器(ESO)的多变量解耦控制方法。将BTT飞行器系统中的耦合视为扰动,利用ESO具有实时跟踪估计扰动能力的特点,将耦合扰动估计出来,通过补偿消除耦合的影响。利用极点配置的方法完成闭环状态反馈控制律设计,并通过数学仿真验证方法的正确性和有效性。
Considering that multivariable coupling problem of bank to turn(BTT)aircraft attitude control system,a multivariable method based on extended state observer(ESO)is proposed.The coupling in the BTT aircraft system is considered as interference,the coupling disturbance is tracked and estimated in real time by ESO,and the coupling effect is eliminated by compensation.The closed loop state feedback control law is designed by means of polar assignment.The correctness and effectiveness of the method are verified by mathematical simulation.
