Implementation method of novel high-performance electronic shaft transmission control system

Abstract

The invention discloses an implementation method of a novel high-performance electronic shaft transmission control system. The method comprises the steps of adopting a one-master multi-slave structure to realize the synchronous coordination control among a plurality of electronic shafts, taking a PC as a master station, and constructing a slave station structure network based on a controller of a slave station interface and a microprocessor DSP chip; enabling each slave station to control the corresponding electronic shaft by controlling a matched driving device; and enabling the master station PC to periodically send a control instruction to the slave station microprocessor DSP through a real-time industrial field bus communication protocol network based on an Ethernet development framework so as to control the electronic shaft driving device, and meanwhile, carrying out high-precision synchronous coordination control on a controlled device in combination with the feedback data. The method has the beneficial effects that the high-precision synchronization can be realized, and the problems of data transmission delay, data packet time sequence disorder, data packet loss and the like caused by a high-speed network technology and the network control for realizing the synchronous coordination can be effectively solved.

Description

technical field [0001] The invention relates to the fields of electronic circuit technology and electric transmission technology; specifically, it refers to a method for realizing a novel high-performance electronic shaft transmission control system. Background technique [0002] At present, in the field of electric transmission technology, the control requirements for electronic shaft multi-axis linkage systems are getting higher and higher, not only high-precision synchronization is required, but also high real-time performance is required. However, most of the existing traditional motor control systems are controlled by analog methods, and there are still problems such as low flexibility, response lag, insufficient accuracy, and zero drift. Although some people have proposed the design of multi-axis linkage control system through communication, most of them use RS-485 bus and CAN field bus. RS-485 bus is the earliest and most widely used serial bus in the field of instru...
