Abstract :
The paper discusses the design and implementation of LMS filter in the MEMS gyro control system in order to improve the precision. The design is established and then simulated using DSP Builder. And the FPGA-based system structure of LMS algorithm is synthesized and simulated on Quartus II platform and Cyclone II family, and the simulation results show that it is reliable and high precision.
