| Abstract: | Based on the characteristics of continuous extrusion and rolling speed control, the improved BP neural network is combined with PID control algorithm, and Siemens S7-200 PLC is adopted to realize the tan- dem mill of motor frequency and speed controls. By comparison with traditional PID and BP neural network PID algorithm, the improved BP neural network PID controller has shorter dynamic response time and good fol- lowing characteristics, which indicates that the method has a good application value in the crowded and rolling speed control. |
