时变大惯量速度同步控制系统

为了保证粗纱的质量，新开发的FA－425型粗纱机计算机控制系统，必须使锭翼和卷绕2台电机在起动、运行和停止全过程中严格保持速度同步。为此，对该系统的数学模型和负载特性进行了研究，通过计算机仿真，提出了多种有效的控制方法和人工智能技术。在该系统中采用了2个速度闭环控制系统，并将其同步误差反馈，实现了双电机的速度同步控制；同时，通过CCD光电传感器将粗纱张力实时反馈到专家控制器，从而保持纱的张力处于某一给定的范围之内。生产应用表明，新型FA－425粗纱机当锭翼最高转速为1400r/min时，在起动、运行和停止阶段锭翼和卷绕两个电机的速度同步误差小于5％。

Speed Synchronization Control System with Time-Dependent Massive Inertia

For quality of the yarn, the new developed computer control system of FA 425 fly frame has to accurately keep the speed synchronization between flyer motor and rolling motor in the process of start, work and stop of the two motors. For this reason, the mathematical model and load specialty of the system were studied. Based on the computer simulation, some effective control methods and intelligent technology were proposed. In the system two close loop speed control systems are used and the speed synchronization control between two motors is realized by means of the feedback of synchronization error. Using CCD photoelectric sensor the tension of yarn feeds back to the expert controller and keeps under the certain precision. The practical production shows that the speed synchronization error of new FA 425 fly frame is less than 5% on the start, going round and stop when the maximum speed of flyer is 1 400 r/min.
