摘　　要：先进复合材料以其高比强度、比刚度以及良好的可设计性获得了广泛应用和迅速发展。复合材料自动铺放技术作为复合材料数字成型的一种典型应用,越来越受到重视。为了解决复合材料自动铺放设备大惯量轴的精密驱动问题,提出交叉耦合结合"PID+前馈+陷波滤波器"的控制方法进行双电机同步协调控制,并给出了在此控制方式下的回原点方法。最后,通过与其他双电机控制策略的比较,验证了该控制方式可以实现无振动、无噪声、稳定精密驱动,满足了大型自动铺放设备的铺放精度。Advanced composite materials （ACM） have been used widely and developed rapidly for their excellent characteristics, such as high specific strength, specific modulus and outstanding designability. As a typical application of composite automatic manufacturing, automated placement has gained more and more attention. In order to resolve the precision driving problem of large-inertia axis of automated placement machine, a method of cross-coupled combining with ＂PID＋feedforward＋notch filter＂ is proposed. With this control mode, a homing method is given. At last, we verify that the double motor driving is precise and stable with no oscillation and noise by comparing with other two control modes.
