为解决飞行/推进综合控制的多变量耦合控制问题,提出了采用自抗扰控制技术的方法.分别对速度控制回路和高度控制回路进行自抗扰控制器设计,将回路间的耦合作为扰动进行估计并抑制.速度控制回路使用二阶线性扩张状态观测器.高度控制回路采用俯仰角和高度内外回路控制,分别使用三阶线性扩张状态观测器.采用带宽来确定状态观测器的参数.仿真结果表明设计的控制器消除了高度和速度通道之间的耦合,具有一定的抗噪声干扰能力.

An active disturbance rejection control (ADRC) scheme was proposed to solve the multivariable coupling control problem of integrated flight-propulsion control.The active disturbance rejection controllers were designed for velocity control loop and altitude control loop respectively.The interaction between flight control and propulsion control was estimated as disturbance and rejected.The second-order linear extended state observer (ESO) was used for velocity control loop.The altitude control loop was treated as internal-external loop control of pitch angle and altitude.Two third-order linear ESOs were proposed in altitude control loop.These ESOs' parameters were adjusted by bandwidth.The simulation results demonstrate that the controller designed eliminates channel coupling of altitude and velocity,and be capable of resisting noise disturbance.
