分数阶PI~λD~μ在高超声速飞行器姿态控制中的应用展望

Prospect of Fractional-Order PI~λD~μ Controller for Hypersonic Missile Attitude Control

高超声速飞行器的发展是一个必然的趋势,但是其具有强耦合、严重非线性、大范围气动环境变化的特点,这对飞行器的姿态控制系统提出了更高的要求。本文简述了现代控制及智能控制在姿态控制器中的应用,回顾了传统PID及其改进控制技术,针对新的被控对象特点,介绍了分数阶PIλDμ及其发展。由于分数阶PIλDμ具有比传统PID更好的鲁棒性和控制性能,展望分数阶PIλDμ控制在高超声速飞行器姿态控制中得到更广泛的应用。

The development of hypersonic missile is an inevitable trend.The requirement of attitude control system for aerocraft is higher because the characteristics of a strong coupling,serious nonlinear and large-scale environmental parameters are changed in aerodynamic.In this paper,the modern control and intelligent control that applied to attitude control are briefed,and classical PID control technology and its improvement are reviewed,the fractional order PIλDμ controller and development for the new object features are also introduced.As a result,fractional order PIλDμ control is better than classical PID control in robustness and control performance.Therefore,the fractional order PIλDμ control will be widely used in hypersonic missile attitude control.
