中文摘要：

针对JWG1728型高速剑杆织机在大卷装卷取过程中存在摩擦盘相对滑动过大、卷布张力不稳定的问题，提出了一种基于伺服电机直接驱动卷布辊的卷取方案。该方案通过实时测量卷布辊半径，利用当前半径值计算出驱动卷布辊所需要的电机转速，进而由控制器驱动伺服电机调速，实现卷绕过程恒张力恒线速度运行的目的。在MATLAB/Simulink开发环境中对卷绕过程进行了建模仿真，当给定纬密后，随着卷取半径的增加，驱动电机转速不断下降，从而保证了织机卷绕线速度的恒定。仿真结果表明，该控制方案达到了卷取过程的预期调速效果，对实际生产具有指导作用。

英文摘要：

The take-up process of JWG1728 high-speed rapier loom is analyzed and some problems are pointed out that loom take-up roll drive will make friction disc have huger relative friction motion when the volume becomes bigger and the stability of tension is inadequate. Aiming at this problem , the servo motor is adopted to drive take-up roll directly. This proposal measures the real-time radius of take-up roll which is utilized to calculate the motor speed that is enough to drive take-up roll and is regulated by servo motor via controller , in order to keep a constant speed and tension during the winding operation. Considering the process that is simulated in MATLAB/Simulink, when weft density is set, with the take-up radius increasing, the speed of motor drive gradually decreases so as to ensure constant take-up linear velocity. The simulation results show that this control scheme can achieve the expected effect in take-up process and provides instruction to actual production.
