Angle Measurement System for Two-speed Resolver Based on FPGA
Jiang Bo · Modern Electronics Technique · 2010
A design scheme of angle measurement circuit for two-speed resolver based on FPGA is introduced,which controls the decoding and synchronization of AD2S82A and AD2S80Athrough FPGA.The error compensation and combination of the converted data and the conversion of binary angle value were carried on by FPGA,in order to improve the integration and reliability of the whole system.The whole circuit was designed in Altium Designer 9.0 design environment.The simulation of FPGA part is based on the chip EP2C35F484C6 of Altera Company,the test and simulation results achieve the design functions of the scheme commendably,and meet the requirement about high-precision,high-speed conversion of the design.
