[0002] In the mechanical equipment for cutting sponge, it is necessary to drive two servo motors at the same time to pull a saw blade and cut the sponge like a saw. Obviously, this needs to control the synchronous rotation of the servo motors, otherwise the knife will be easily broken. At the same time, the mechanical part of the equipment will be greatly damaged, seriously affecting the stability and service life of the electromechanical equipment, so the synchronous control of the servo motor is the key

[0003] At present, there are materials that disclose a synchronous operation control system, which uses an encoder to detect the motor speed in real time, and calculates the rated speed of the main motor and the rated response speed of each slave motor through a programmable controller. The number of generated pulses is output to the synchronous control card of each frequency converter in real time, and the control motor responds in real time. Compared with the traditional method, the degree of component integration is improved, command control can be realized, and the connection line is relatively simplified. However, this method The cost is high, the degree of component integration is not high enough, and the failure rate is relatively high
