摘要:
针对逆变器供电的电动机驱动系统信号处理中存在的复参数估计问题，研究复参数最小二乘估计算法，提出一种加权遗忘因子的复参数最小二乘估计方法（WFCRLS）。利用对称分量理论，对驱动系统信号进行分析，获得由多阶正序对称谐波分量构成的驱动系统信号数学模型，利用WFCRLS，实现了驱动系统输出信号的谱估计。通过与加窗快速傅里叶变换谱分析结果对比，证明本文方法谱估计结果的有效性。
Abstract:
Aimed at complex parameter estimation of signal with inverter-fed motor drives ，complex recursive least square algorithm is studied，and the complex weighted forgetting factor recursive least square (WFCRLS) algorithm is presented.The output signal of the inverter-fed motor drive system is analyzd by applying theory of symmetrical components，the mathematical model composed of multiple positive symmetrical (PS) components harmonics withe the drives is obtained，the WFCRLS can be used to estimate the spectral of the drives signal.Comparing the results with those obtained by window FFT，it shows that the method proposed in the paper is effective.
