摘　　要：为解决伺服凸轮式压力机由于传动偏载或扭矩分配不均产生的传动系统严重的非线性振动问题,提出在凸轮轴两端各采用一个伺服电机实现双电机同步驱动来提高凸轮-滚子传动系统的可靠性,并提出基于自抗扰扭矩分配算法的交叉耦合同步控制策略,该策略将双电机的速度同步误差输入至同步控制器,通过权值变化规律调整权值,直至达到性能指标要求。仿真结果表明:与传统交叉耦合控制系统相比,基于自抗扰扭矩分配算法的同步控制策略的抗干扰能力强、跟踪响应速度快、同步控制精度更高、达到速度同步的时间更短,位置同步误差小于0.02 mm。仿真结果不仅验证了伺服凸轮式压力机双电机同步驱动策略的有效性,还为解决伺服凸轮式压力机的控制问题提供了可行方案。To solve the problem of severe nonlinear vibration in the transmission system caused by biased load of transmission or uneven torque distribution in servo cam pressure,therefore,a dual-motor synchronous drive strategy using a servo motor at each end of camshaft was proposed to enhance the reliability of cam-roller transmission system,and a cross coupling synchronous control strategy based on the active disturbance rejection torque allocation algorithm was introduced.This strategy took the speed synchronization error of dual-motor as input to the synchronization controller,and adjusted the weight values according to predetermined variation laws until the performance index requirements were met.The simulation results demonstrate that compared to the traditional cross-coupling control systems,this synchronous control strategy based on the active disturbance rejection torque allocation algorithm exhibits superior anti-interference capabilities,faster tracking response speeds,higher synchronization control accuracy and shorter time required to achieve speed synchronization,and the position synchronization error is less than 0.02 mm.The simulation results not only verify the effectiveness of the dual-motor synchronous drive strategy for the servo cam press,but also provide a feasible solution to the control problem of the servo cam press.
