Abstract
- This study concentrates on the parameter estimation of multivariate pseudo‐linear autoregressive moving average systems by means of the multi‐innovation identification theory and data filtering technique. A multi‐innovation stochastic gradient algorithm is derived by introducing the innovation length in the stochastic gradient algorithm. Then, the original system is transformed into two subsystems by using a filter. A filtering‐based multi‐innovation stochastic gradient algorithm is presented, whose parameter estimation accuracy is higher than the multi‐innovation stochastic gradient algorithm. The simulation results confirm that these two algorithms are effective. [ABSTRACT FROM AUTHOR]
