Design and simulation of the digital controller of digital closed loop fiber optic gyroscope based on Matlab

Current research on the digital controller of digital closed loop fiber optic gyroscope (FOG) is mainly concentrated on integral (I) controller and proportional integral (PI) controller. Little work has been done to improve the performance of the system under dynamic conditions and to reduce the tracking error of FOG under the condition of the ramp angle speed signal input. It is necessary to change the digital controller of the closed-loop FOG for reducing the track error in actual applications of ramp signal input. Matlab is used to design and simulate the digital controller of the closed-loop FOG. Finally, simulation of the controller is performed by Matlab to demonstrate the efficiency of the changed digital controller of the closed-loop FOG.
