Method of gyro control based on DSP+FPGA system

A method of gyro control based on DSP + FPGA system is introduced. Two critical problems, the imprecise measure of the frequency and phase of the gyro reference signal which results in the gyro drift in the control course, are solved using this method. The precise measures of the frequency and phase of the gyro reference signal can be obtained in FPGA. By exchanging the data between DSP and FPGA, the frequency and phase of the gyro reference signal and the gyro precession signal can be calculated in DSP, so the algorithm is a fast, real-time and easy-to-update control algorithm. Experimental results show that the method can quickly guide the gyro to track the target with small drift. Therefore, it has a high practical value in missile guidance.
