Abstract

The invention discloses a control system for a servo press, and belongs to the technical field of electromechanical control. The control system for the servo press comprises an ARM9 microprocessor submodule and an FPGA submodule, wherein the ARM9 microprocessor submodule and the FPGA submodule carry out communication through a bus, the ARM9 microprocessor submodule is used for reading sliding block position information output by a position detection device, obtaining the theoretical speed of a sliding block at the position according to the sliding block position information, and transmitting the theoretical speed of the sliding block to the FPGA submodule, and the FPGA submodule uses a three-level series connection fuzzy PID control structure to have control over a servo motor. Further, the ARM9 microprocessor submodule comprises a real-time embedded operating system with combination between the Linux and the Xenomai. Compared with the prior art, the control system for the servo press has the advantages of being low in cost, compact in software and hardware resource, low in power consumption, good in real-time control performance and high in accuracy.

Description

technical field [0001] The invention relates to a servo press control system, which belongs to the technical field of electromechanical control. Background technique [0002] Most of the current servo press control systems use a personal computer or an industrial computer combined with a motion control card in the upper computer and lower computer mode, and use a general-purpose operating system, such as windows, Linux and other operating systems. This method can combine the openness and Combining the information processing capability with the motion processing characteristics of the motion control card, it is easy to upgrade and expand, but this method also has the disadvantages of high cost of the control system, serious waste of hardware resources, and high power consumption. At the same time, in the development process of servo presses, how to improve the accuracy of servo presses and achieve fast and stable response has always been the focus of research on servo presses...
