摘　　要：襟缝翼机电作动器是飞机高升力系统中的关键运动部件,其速度控制对襟缝翼的姿态调节十分重要。然而,襟缝翼机电作动器易受到翼面周期性或非周期性气动载荷干扰,传统的比例积分型速度控制器性能实现受限。为此,本文提出一种基于比例谐振自抗扰控制器(ADRC),在抑制非周期性干扰基础上还可抑制特定次周期性干扰。周期性干扰通过采用比例谐振控制的扩展状态观测器来估计。通过试验,比较了比例积分型控制器、传统线性自抗扰控制器和比例谐振型自抗扰控制器的控制性能,验证了本文所提出的方法可以显著抑制干扰、提高机电作动器的速度控制精度,为飞机平稳起降提供技术支撑。Flap-slat electromechanical actuator is a key motion part in the aircraft high lift system,and its speed control is very important for the opening and closing precision of the flap-slat.However,the speed control loop of electromechanical actuator is prone to periodic or aperiodic interference of external aerodynamic load and the traditional proportional integral speed controller cannot guarantee satisfactory control performance.Therefore,a speed controller based on a proportional resonance Active Disturbance Rejection Control(ADRC)is proposed.It can not only suppress aperiodic interference but also suppress specific periodic interference.The periodic interference is estimated by an extended state observer using a proportional resonance term.By comparing the control performance of proportional integral controller,traditional linear ADRC controller and proportional resonant controller,it is proved that the proposed method can significantly suppress the interference,improve the control performance of flap-slat electromechanical actuator,and enhance the smoothness of aircraft take-off and landing.
