Control System Design Of Servo Motor

The effective control of the servo motor is the the key of servo press molding, theprecise control of the motor speed is is beneficial to the improvement of the quality of themolded parts, and the communications in a timely manner conducive to improve theaccuracy of the whole system, the real-time feedback of the user interface on themachining data greatly improved visualization and controllable. So it is necessary tooptimize the traditional presses molding system, these important factors effective andreasonable combined.This article on permanent magnet AC servo press forming process for the designrequirements, setting a control system about embedded, modular, networked, based on theSTM32F103C8controller and QT programming software. Including on-site debuggingmodule, motion control module, the man-machine interface module, as well as datastorage module. System control processing site in the remote terminal and monitor productquality, HMI displayed in real time the current motor running, control of high precision,reliability. The contents of the control system is:Firstly, Design the file system based on SD memory card with SPI, you can save thedata in the host computer, and provide a reference for the follow-up system upgrades andmaintenance.Secondly, hardware design and software design. The man-machine interface moduleuses a relatively new QT software development; motion control module based the STM32,mainly generate signals to control the motor driver, encoder feedback link was added inorder to ensure precise control; LCD module with LCD screen, debug motor sport throughthe key scene.Lastly, TCP/IP communications networks, remote data communication between hostcomputer and the next machine, remote video transmission based on OpenCV site.
