【摘要】：针对倾斜转弯(Bank-to-turn,BTT)飞行器俯冲段制导与控制系统设计中存在的强耦合、强非线性问题,研究考虑通道耦合因素的制导与控制一体化设计方法。首先建立了考虑控制通道间耦合因素的三维制导与控制一体化设计模型,在模型中引入不确定性因素,采用连续非光滑控制理论对三维块系统设计非光滑扩张状态观测器(Non-smooth extended state observer,NESO)进行观测补偿,然后结合反步法与块动态逆方法设计可以保证有限时间收敛的制导与控制一体化算法,并严格证明了带有扩张状态观测器的级联系统是全局有限时间稳定的。提出的方法适应强耦合BTT飞行器存在扰动情况下的快时变控制需求,通过仿真校验该方法可行、有效。
[Abstract]:Aiming at the problem of strong coupling and strong nonlinearity in the design of guidance and control system for subduction section of Bank-to-turn,BTT aircraft, the integrated design method of guidance and control considering channel coupling factor is studied. Firstly, a three-dimensional integrated guidance and control design model considering coupling factors between control channels is established, and uncertainty factors are introduced into the model. The continuous nonsmooth control theory is used to compensate the design of a nonsmooth extended state observer (Non-smooth extended state observer,NESO) for a three-dimensional block system. Then the integrated guidance and control algorithm which can guarantee the finite-time convergence is designed by combining the back-step method and the block dynamic inverse method. It is proved strictly that the cascade system with extended state observer is globally finite-time stable. The proposed method adapts to the requirement of fast time-varying control in the presence of disturbance of the strongly coupled BTT aircraft. The simulation results show that the method is feasible and effective.
