Micro-machined quartz tuning fork gyroscope as the speed feedback system in vehicle steering system, its output noise and random drift directly affect the final stable precision. In response to this problem, an adaptive forward predictive filtering method is proposed to eliminate gyro noise, and an incremental or decreasing variable is introduced into the velocity closed loop system according to the error of the angle value of the grating and the initial stable angle. The actual tests verify that the method can improve the stable precision to±7.2″, which verifies the effectiveness of the method.
