摘要
随着速率型光纤陀螺在稳定平台、导引系统及相敏捕获等随动控制领域的应用越来越广泛,系统对其带宽、相位滞后和瞬态噪声提出了越来越严苛的要求。带宽反映了载体的跟踪速度,相位滞后反映了载体的跟踪效率,瞬态噪声决定了载体的控制精度,既相辅相成又互有制约。本文以某工程中陀螺稳定控制平台为应用背景,分析了影响光纤陀螺带宽的主要因素,探讨了影响速率型光纤陀螺带宽、相位滞后及瞬态噪声的关系,并给出了闭环光纤陀螺带宽的测试方法。根据设定的带宽、相位滞后和瞬态噪声要求,在理论分析的基础上,通过MATLAB工具箱,选取了基于Kaiser窗设计的FIR滤波器,满足了应用需求,并为其他速率型光纤陀螺在随动控制领域的应用提供了设计依据。
With more and more wide use of the rate-output FOG in the servo control fields of stabilized platform, navigation system and phase sensitive capture, bandwidth, phase lag and transient noise of the system are proposed more and more stringent requirements. The bandwidth reflects the tracking speed of system, and the phase lag reflects the tracking efficiency of the system, and the transient noise determines the control precision of system. They are restricted and affected each other. Based on a project in gyro-stabilized control platform, this paper analyzes the main factors which influence the bandwidth of FOG, and discusses the relationship between bandwidth, phase lag and transient noise, and gives the test method of closed loop bandwidth of FOG. According to the requirements of setted bandwidth, phase lag and transient noise, on basis of the theoretical analysis, and through the Matlab toolbox, the Kaiser window are selected to design FIR filter, which meets the application requirements, and probides design base of the rate-output FOG in other dervo control fields.
