Abstract

The invention discloses a dual-motor synchronous control system, which comprises a master unit, a first frequency converter, a first position coder, a second frequency converter, a second position coder and a master controller, wherein the master unit is used for inputting a user instruction; the first frequency converter and the first position coder are connected with a first motor; the second frequency converter and the second position coder are connected with a second motor; the master controller is connected with the master unit, and comprises a controller and four communication lines connected with the controller; the controller is a control algorithm software program run on the master controller; and the four communication lines comprise a first communication line connected with the first frequency converter, a second communication line connected with the first position coder, a third communication line connected with the second frequency converter and a fourth communication line connected with the second position coder. By an implementation method for the dual-motor synchronous control system provided by the invention, the first and second motors meet position synchronization running requirements; high motion control accuracy and the relatively higher flexibility of the system are achieved; and simultaneously, the system and the method have the advantages of operating simplicity, low cost and the like, and are easy to popularize.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a dual-motor synchronous control system and an implementation method thereof. Background technique [0002] In high-precision, high-speed transmission systems such as papermaking, printing and dyeing, textile and CNC machine tools, multi-motor synchronous control has always been the core issue. The quality of motor synchronous control directly affects the reliability of the system and the quality of the product. [0003] In the existing motor synchronous control technology, the status of the motor in the synchronous system is the same: its operating conditions, response speed and load conditions are basically the same. When performing motor synchronous control, using the same control method can make multiple motors realize synchronous operation. However, with the basic of numerical control technology, the position of multi-motor in synchronous system is very different in ...
