Sampling System Based on DSP I/O Space and Resolver

This article describes an implementation of position control system in the shaft—the design of digital conversion. It can be applied to the system that need for accurate position. The core technology is the use of rich I/O space of DSP and the rotary transformer and the high-precision converter. Compared to the conventional position control system, the program simplifies the complexity of the system, reduces costs and increases the processing speed of the system. It is suitable for real-time signal processing; what’s more, its reliability and versatility have been greatly improved.
