| Abstract: | Based on the characteristics of parallel processing and plenteous IO interfaces of FPGA, the combined data acquisition and control system was designed for the strapdown inertial navigation system. The system can execute the real-time acquisition and processing of IMU and GPS data needed by SINS, and generate PWM control signals with arbitrary duty cycle based on the requirement. The system presets plenteous IO interfaces to connect DSP and other processors. The testing results show that the system designed with this method has small volume, high reliability and better real-time performance. |
