리졸버의 실시간 각도 정보 획득을 위한 펌웨어 모듈 구현

This paper contains the firmware solution to obtain angle information from Resolver mounted on infrared sensor. The proposed firmware solution is following. First, selecting adequate modulator and Sinc Filter is important to meet high accuracy of angle and fast system response. Second, design VHDL with Mealy State Machine for FPGA to react various situation and to control Resolver circuit. Third, Applying FIR filter to minimize change Angle information.
