Servo control system

The utility model relates to a servo control system which used in the casting and rolling method for the copper tube production line. It comprises a signal input, a control operation, an actuator and a load. The utility model is characterized in that: the control system is a closed loop servo-control system which comprises a slaving transformer, a servo controller, a servomotor, an output signal feedback device and a gear drive element. An industry power goes through the slaving transformer to provide the required power to the servo controller. An input signal and a feedback signal are processed into an output signal which achieves accurate control effect by the servo controller. The output signal of the servo controller in the form of advance -wait -back -wait -back -wait -advance controls the servomotor. The servomotor drives a gear driving element and the load. The utility model realizes the closed loop control over the position, the speed and the moment of force. It has good high-speed performance, strong anti-overload capacity and stable running process. Dynamic response time of the acceleration-deceleration of the electromotor is short and achieves accurate control effect. The utility model overcomes the disadvantages of high failure rate and poor precision in the prior art andit lowers the maintenance cost.
