Abstract:In order to further improve the performance of MEMS gyroscope, a novel demodulation algorithm all-phase Fast Fourier Transform (apFFT) based on FPGA is proposed to the digital control system, in which the drive detection signal and sensitive axis signal are demodulated respectively. Combining with automatic gain control (AGC) and phase-locked loop (PLL), the closed-loop drive control and high precision demodulated output of MEMS gyroscope have been implemented. A printed circuit board based on FPGA is manufact… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
