Compared with the traditional mechanical gyroscope, the fiber optic gyroscope has the advantages of wide dynamic range, low cost, small size, light weight and high reliability. 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 fuzzy self-adapting proportional-integral-derivative (PID) controller is designed. The simulation results show that the controller can enforce the robustness of system, reduce the regulation time and improve the dynamic performance of IFOG effectively.%光纤陀螺与传统的机械陀螺相比,具有动态范围大、成本低、体积小、可靠性高等优点.数字闭环干涉式光纤陀螺(IFOG)的动态性能受控制系统设计的影响.现根据光纤陀螺数字闭环检测过程,建立了控制系统的数学模型,设计了模糊自适应PID控制器.仿真结果显示,设计的控制器能够有效地增强系统的鲁棒性,缩短调节时间,改善系统的动态性能.
