飞机纵向姿态自抗扰控制器的设计及参数优化

Auto-disturbances-rejection controller design and its parameter optimization for aircraft longitudinal attitude

将自抗扰控制器用于飞机的纵向姿态控制。在自抗扰控制器(ADRC)参数优化方面,根据参数变化对系统性能的影响,采用二进制遗传算法自动优化,弱化了ADRC参数整定对经验的依赖程度。在两种飞行状态下的仿真及抗干扰测试表明,控制器具有较强的鲁棒性和抗干扰性,系统具有良好的动态和稳态性能。

The auto-disturbances-rejection controller （ADRC） is proposed to design controller for aircraft longitudinal attitude. According to the influence to the system performance when parameter changing, the parameters were self-adjusted by GA. This method doesn’t depend on the experience of human heavily. Without changing the structure and parameters of the controller, the simulation results indicate that it achieves robustness performance and anti-disturbance performance for the controller, high dynamic performance and steady state performance for the system in two different flight states.
