Abstract :
This paper considers the parameter estimation problems of output error autoregressive (OEAR) systems based on the maximum likelihood principle and the gradient search principle. A maximum likelihood forgetting factor stochastic gradient algorithm and a maximum likelihood iterative gradient identification algorithm are developed. The simulation results show that the proposed algorithms can effectively estimate the parameters of the OEAR systems.
