A New Era of Servo System Structure: The SoC-Based Multi-Axis Control-Drive Integration Platform

Nowadays, the System on Chip (SoC) based multi-axis control drive integration platform has been a good alternative to the classic distributed servo system structure. Compared with the distributed structure, the integration structure can reduce the manufacturing cost, achieve a faster internal information sharing, and has richer resources of multi-class chips. Hence, SoC-based integration platforms have greater potential and better control performance. In this paper an easy-to-follow SoC-based multi-axis control-drive integration platform design method is presented at first. The hardware design and software structure are discussed in detail. Then, based on the SoC-based platform, several control performance improvement strategies are listed out to verify the advantages of the SoC-based integration platform. The results of the analyses and experiments show that SoC-based integration servo system structure can be a good technology carrier for the advanced servo system in future.
