摘要
基于功能安全的需求分解,通过英飞凌AURIX MCU将Δ-ΣADC和SAR ADC同时用于旋转变压器的软件解码中,互为冗余。对Δ-ΣADC和SAR ADC外设模块分别进行了详细配置,实现了包络面的解析,设计了观测器对获取的包络面进行锁相解码,并对两种解码方式分别设计了矫正环节。通过台架实验验证了该方案的可行性。
By Infineon AURIX MCU,delta-sigma ADC and SAR ADC were simultaneously used in resolver decoding which were mutually redundant.Delta-sigma ADC and SAR ADC peripheral module were configured in detail to achieve envelope surface analysis.An observer was designed to decode the obtained envelope,and a delay compensation link was designed for the two decoding methods.The feasibility of the scheme was verified by bench test.
