The application and implement of S-shape curve of speed control of skin pass mill, the control principle and implement of automatic speed down during skin pass rolling, the smooth switch-over between tension control and speed control of coiler, the configuration of control system are described. 叙述S型曲线在平整机速度控制中的应用及实现方法,平整过程中的自动制动控制原理及实现方法,卷取机速度控制与张力控制的平滑切换,控制系统的构成。
By using the multi-mode measuring methods and the on-axis tracking control technique, the stability of automatic tracking, tracking accuracy and the comprehensive tracking performance of the theodolite can be improved. At the same time the smooth switch-over among several tracking modes can be carried out. 利用误差跟踪控制和共轴跟踪控制技术的多模控制方式,可以提高系统自动跟踪的稳定性、跟踪精度和各工作方式间的平滑切换,使整个系统的综合性能得到完善。
