  • Research-AR-on-vibration-signals
    本算法程序基于实测汽轮机振动信号进行了测试及性能分析。理论分析及仿真结果表明,AR模型谱估计算法在阶次合适的情况下,能够取得较好的方差及分辨力性能,适合于振动信号的功率谱估计,且AIC准则为确定合理的模型阶次提供了有效依据。(This algorithm based on the measured turbine vibration signal testing and performance analysis. Theoretical analysis and simulation results show that, AR model spectrum estimation algorithm in appropriate circumstances the order, the variance can achieve better performance and resolution, suitable for vibration signal power spectrum estimation, and the AIC criterion to determine a reasonable model order provides an effective basis.)
