摘　　要：采用转速和张力的闭环控制。在给定的线速度下,协调控制牵引电机和卷取电机的转速,实现卷取电机转速跟随牵引电机的转速变化。转速的控制和张力的控制都采用PID控制。The loop control of the rotate speeds and the tension is adopted. The rotate speeds of the traction motor and the rolling motor are harmoniously controlled in the precondition of the fixed line speed. The rotate speed of the rolling motor is changed along with the rotate speed of the traction motor. The control of the rotate speeds and the control of the tension are all carried out by the PID controller.
