Abstract: Based on the hierarchical identification principle, this paper introduces the hierarchical least squares identification algorithm, the hierarchical multi-innovation least squares identification algorithm, the hierarchical stochastic gradient identification algorithm, the hierarchical multi-innovation stochastic gradient identification algorithm, the hierarchical recursive gradient identification algorithm, the hierarchical multi-innovation recursive gradient identification algorithm for linear regressive 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; linear regressive model
