摘要: 针对有限脉冲响应滑动平均系统,利用递阶辨识原理,研究了递阶增广随机梯度算法、递阶多新息增广随机梯度算法、递阶增广梯度算法、递阶多新息增广梯度算法、递阶增广最小二乘算法、递阶多新息增广最小二乘算法等。这些辨识方法可以推广到有色噪声的随机系统中。

Abstract: Based on the hierarchical identification principle, this paper studies the hierarchical extended stochastic gradient algorithm, the hierarchical multi-innovation extended stochastic gradient algorithm, the hierarchical extended gradient algorithm, the hierarchical multi-innovation extended gradient algorithm, the hierarchical extended least squares algorithm, and the hierarchical multi-innovation extended least squares algorithm for finite impulse response moving average systems. These methods can be extended to stochastic systems with colored noises.
Key words: parameter estimation; recursive identification; multi-innovation identification; hierarchical identification; least squares
