谐振式光纤陀螺自抗扰控制锁频方法研究
Research on Frequency Locking Method of Active Disturbance Rejection Control for Resonator Fiber Optical Gyro
摘要
Abstract
In resonator fiber optical gyro(RFOG)system,the center frequency of the laser can be locked at the resonant frequency point by using the frequency locking technique,so that the gyro angular velocity can be measured.At present,the PI control method commonly used for frequency tracking and locking is more suitable for linear systems.For the nonlinear RFOG system,in order to improve its an-gular velocity tracking capability and locking accuracy,the active disturbance rejection control(ADRC)method is introduced,and a Sim-ulink system is built for model comparison.The simulation results show that compared with PI control method,ADRC method can obtain the same frequency locking time and dynamic range.When the system has angular velocity input,the tracking ability of ADRC method is better,the angular velocity detection accuracy is improved by an order of magnitude compared with PI control,which provides ideas for future engineering applications.关键词
