Secondly, two classical models of distributed parameter DLSP: power frequency model and time-domain model. Based on these twomodels dynamic phasor model has been deduced.
The three basic problems of two-dimensional (2-d) hidden Markov models (HMMs) are studied, including probability evaluation, optimal states and parameter estimation.
研究了2维隐马尔可夫模型的三个基本问题,包括概率评估问题、最优状态问题和参数估计问题。

In practice, the parameters of these models may change with time over a wide range. Two on-line parameter estimation methods are discussed in this paper.
