Abstract

The invention discloses an AC servo control system, and belongs to the technical field of motors. The AC servo control system comprises a control board (1) and a power board (2). A problem that the AC servo control system is compatible with various encoders is solved. A high-performance servo control system adopting a DSP and an FPGA as a control platform is realized.

Description

technical field [0001] The invention belongs to the technical field of motors. Background technique [0002] Since the end of the 1980s, with the development of AC servo motor technology, the AC motor control theory has continued to mature. In just three decades, the AC servo system has achieved tremendous development. With the development of frequency conversion speed regulation technology of AC motors, the position servo control of AC motors has a wide debugging range, high-precision control capabilities, fast dynamic response capabilities and technical performance of four-phase limit state operation. Or the static characteristics can be comparable with the DC motor control system. In today's AC motor control, especially the position servo control of AC motors, it is still one of the hotspots in academic and industrial research. [0003] At present, there are many kinds of encoders for AC servo motors on the market, such as digital incremental encoders, digital absolute ...
