Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a winding control method provided in the present application, where the winding control method is applied to a winding system, the winding system includes a winding motor, and the method includes:
step 11: and receiving a control instruction, and controlling the winding motor to operate according to the control instruction.
After the power is on, an instruction for controlling the winding motor to operate can be received, and the instruction can be generated by operating the winding system by an operator.
Step 12: and receiving a preset tension value, carrying out closed-loop regulation according to the preset tension value and the collected tension signal, and controlling the winding motor so that the rotating speed or the torque of the winding motor is within a preset range.
The tension control method can be divided into a direct tension control method and an indirect tension control method, and the direct tension control method is also called a feedback control method and can be divided into two methods: one is to use a sensor to detect the actual tension and use the measured value as a feedback signal to form a tension closed loop system, i.e. the measured actual value is compared with the preset tension, and the deviation generates a control action to make the actual tension equal to the preset tension; and the other method is to utilize the loop to establish tension, measure loop quantity, form a loop feedback control system and control the loop quantity to be constant so as to ensure that the tension of the product is constant.
The indirect tension control method is also called a compensation control method, compensates tension change which may occur by adjusting parameters influencing the tension stability, and indirectly keeps the tension stable, namely only setting a preset tension value, a detector is not needed to acquire an actual value of the tension, closed-loop control is not formed, and the tension is indirectly and constantly controlled by controlling the current or exciting current of the motor, so that the torque of the motor is kept unchanged, and the tension is guaranteed to be constant.
In the embodiment, a direct tension control method is adopted, tension feedback adjustment is added on the basis of tension open-loop control, a preset tension value set by an operator can be received, closed-loop adjustment is performed according to the preset tension value and a sampled simulated tension signal, a constant tension value is output, and the constant rotating speed or torque of the winding motor is ensured.

Referring to fig. 2, fig. 2 is a schematic flow chart of another embodiment of a rolling control method provided in the present application, the method including:
step 21: and receiving and storing the parameters of the winding motor.

Step 22: and receiving a control instruction, and controlling the winding motor to operate according to the control instruction.
The control instruction generated by operating personnel operating the human-computer interaction equipment can be received, the control instruction comprises an operation instruction, a stop instruction, a fault reset instruction or an emergency stop instruction, and after the operation instruction is received, the winding motor can be controlled to operate.
Step 23: and receiving a preset tension value, and sampling the tension signal to obtain a feedback tension value.
After the winding motor is started, a preset tension value set by an operator through the human-computer interaction device can be received, and proportional-Integral-derivative (PID) closed-loop adjustment is performed, specifically, in steps 23 to 26.
Step 24: and calculating the tension deviation between the preset tension value and the feedback tension value.
The tension deviation is the difference between the preset tension value and the feedback tension value, and can be adjusted according to the tension deviation, so that the output tension value gradually approaches a fixed tension value.
Step 25: and performing proportional integral derivative operation according to the tension deviation, and outputting a constant tension value.
Performing proportional adjustment calculation according to the deviation between the feedback tension value obtained by sampling and a preset tension value and a proportional coefficient, then performing integral adjustment calculation according to the proportional coefficient, the tension deviation and an integral time, and finally performing differential adjustment calculation according to a differential time and the proportional coefficient, as shown in fig. 3 specifically:
