Problems solved by technology
[0008] The traditional multi-motor control synchronization adopts the independent control of multiple motors. The control strategies involved are all aimed at each axis, that is, the motor targeted by the axis, and are invisible to other motors. Although effective control strategies are adopted in the To some extent, the control effect can be improved, but there are still great limitations for the coordinated control of the entire multi-motor system

The invention discloses a dual-motor-driven load synchronization control system. A first servo driver is used for driving a first electric cylinder to work under the control of a control processor; asecond servo driver is used for driving a second electric cylinder to work under the control of the control processor; the first electric cylinder and the second electric cylinder drive a first powerinput connecting rod and a second power input connecting rod corresponding to the load to act synchronously; a first position sensor is used for obtaining actual position of the first power input connecting rod of the load, and transmitting the actual position of the first power input connecting rod of the load to the control processor through a first data acquisition module; and the second position sensor is used for obtaining actual position of the second power input connecting rod of the load, and transmitting the actual position of the second power input connecting rod of the load to the control processor through a second data acquisition module. The positions of the two power input connecting rods of the load can be adjusted precisely to enable the two power input connecting rods to act synchronously.
Description
technical field [0001] The invention relates to the technical field of dual motor synchronous control, in particular to a dual motor driven load synchronous control system and control method. Background technique [0002] In recent years, with the development of industry, the requirements for various mechanical properties and product quality have been gradually improved. In some occasions, the control of only one motor can no longer meet the requirements. People need to control multiple motors to make them better. Coordinated operation. [0003] With the development of science and technology, the method of realizing motor synchronization is constantly developing, and its development process can be roughly divided into three stages: [0004] The first stage: rigid transmission or flexible transmission to achieve synchronization; [0005] The second stage: vibration synchronization or electric shaft synchronization; [0006] The third stage: control synchronization or compo...
