摘　　要：卷到卷(roll-to-roll,R2R)制程普遍应用于柔性材料的量化生产中,其套色精度是产品质量的关键因素。R2R制程是一个多输入多输出、强耦合的复杂生产过程,实现高速高精度套色控制是其基本要求。首先,根据R2R印刷系统的状态空间模型,设计了基于降维观测器的状态反馈控制方法,同时通过粒子群优化算法对状态反馈的极点进行优化,实现了套色误差的高精度控制。将提出的套色控制方法与最新发表的全解耦比例微分(fully decoupled proportional-derivative,FDPD)套色控制方法进行对比,所提方法在套色精度上获得了50%~80%的提升,调节时间缩短了50%~65%,控制量绝对值之和仅为FDPD控制方法的46%~57%,这不仅减少了对执行机构的冲击,也节约了能量。对比结果证实了降维观测器的估值准确性,也表明所提方法能够明显提高控制性能。Roll-to-roll(R2R)manufacturing process is widely used in the mass production of flexible materials,and its register accuracy is a key factor in product quality.R2R manufacturing process is a complex MIMO production process with strong coupling.Achieving high-speed and high-precision register control is a basic requirement for R2R manufacturing process.According to the state space model of R2R printing system,state feedback control method is designed based on the reduced-order observer.At the same time,the poles of the state feedback are optimized through the particle swarm optimization algorithm to achieve the high-precision control of the register error.Compared with the newly published fully decoupled PD(FDPD)control method,the proposed register control method has a 50%-80% improvement in register accuracy and a 50%-65% improvement in adjustment time.The sum of the absolute values of the control quantity is only 46%-57% of the FDPD control method,which not only reduces the impact on the actuator,but also saves energy.The comparison results confirmed that the estimation of reduced-order observer is accurate,and the control performance has been significantly improved.
