| Abstract: | The fiber optic gyroscope′s research and development is focused on engineering application. The design of the controller system has a serious influence on the dynamic performance of digital closed-loop interferometric fiber optic gyroscope(IFOG). According to the digital closed-loop test process of the IFOG, the mathematical model of the controller system is built, and a digital proportional-integral-derivative (PID) controller and a infinite impulse response (IIR) filter are analysed and designed carefully. The simulation results show that the controller can improve the output-bandwidth of system and the dynamic performance of IFOG effectively. |
