针对高速列车升力翼中双电机协同控制攻角高精度控制的问题,提出了一种基于改进型自抗扰控制器的新型控制策略。该策略改进位置环,并将交叉耦合结构中的位置误差反馈至电流环,实现高精度控制,从而解决高速列车升力翼系统在实际应用中存在的滞后性以及抗干扰能力弱等问题。通过MATLAB/Simulink仿真验证该方法的快速响应能力、抗干扰能力以及电机同步效果。仿真结果表明,在给予不同负载扰动的情况下,该方法能够极大地提升系统的响应速度,且抗干扰能力与同步效果优异,能够帮助高速列车升力翼实现高精度的攻角变换。

[Abstract]
Aiming at the problem of high-precision control of the angle of attack controlled by dual motors in the lift wing of high-speed train, a new control strategy based on an improved active disturbance rejection controller is proposed. This strategy improves the position loop and feeds the position error in the cross-coupling structure back to the current loop to achieve high-precision control, so as to solve the problems of hysteresis and weak anti-disturbance ability of the high-speed train lift wing system in practice. The fast response ability, anti-disturbance ability and motor synchronization effect of this method are verified by MATLAB/Simulink simulation. The simulation results show that under the condition of different load disturbances, this method can greatly improve the response speed of the system, and its anti-disturbance ability and synchronization effect are excellent, which can help high-speed train lift wing achieve the high-precision angle of attack transformation.
