摘　　要：针对电磁直线执行器系统内部参数扰动和外部不确定性干扰对控制系统的影响,提出了一种变论域双模糊自抗扰控制方法。设计了内电流环采用PI控制,而位置环采用变论域双模糊自抗扰控制的双闭环控制。在不改变输出论域划分的前提下,以一级模糊控制的输出作为伸缩因子,灵活调节二级模糊控制的输出论域,使得模糊控制具有自适应性,提高了控制系统的稳定性和抗干扰能力。研究结果表明,与现有控制方法相比,文章所提出的控制方法不仅具有较好的轨迹跟踪能力和控制精度,并对系统内外部不确定性扰动具有良好的鲁棒性。A variable-domain double fuzzy active disturbance rejection control method is proposed for the influence of internal parameter disturbances and external uncertainty disturbances on the control system of the electromagnetic linear actuator system. A dual closed-loop control with PI control for the inner current loop and variable-domain dual fuzzy self-rejecting control for the position loop is designed.Without changing the output domain division, the output of the primary fuzzy control is used as the scaling factor to flexibly adjust the output domain of the secondary fuzzy control, which makes the fuzzy control adaptive and improves the stability and anti-interference capability of the control system.The research results show that compared with the existing control methods, the proposed control method not only has better trajectory tracking capability and control accuracy, but also has good robustness to the internal and external uncertainty disturbances of the system.
