摘要
针对俯仰通道的过载控制,提出了控制回路的自抗扰控制设计方法。俯仰通道具有不确定性,利用两个降阶线性扩张状态观测器对系统的不确定性进行实时估计并予以动态补偿,使控制对象化为"积分器串联型",再设计比例控制。仿真结果表明,与PID相比,ADRC具有较强的抗干扰能力,以及较高的控制品质。
This paper presents an active disturbance rejection control for overload control.Double linear extended states observers are proposed for on-line estimating and compensating the dynamics which lumps the internal dynamics and the external disturbance.The plant dynamics is reduced to a group of integrators with LESO,and proportion controller is used.The hardware-in-the-loop simulation results show the control system designed has more excellent character than PID controller.
