| Abstract: | An angle measuring system based on resolver AD2S80A was used for measurement of shaft angle position of elec-tromagnetic coupling displacement sensor. The system working principles,hardware composition and correlative parameter are in-troduced. The design of interface between the system and DSP is researched. The latch is used to eliminate the time delay occur-ing when DSP reads AD2S80A data. Therefore,the real-time performance of the servo control system was improved. |
