Least-squares based and gradient based iterative parameter estimation algorithms for a class of linear-in-parameters multiple-input single-output output error systems

Abstract

The identification of a class of linear-in-parametersmultiple-input single-output systems is considered. By using the iterative search, a least-squares based iterative algorithmand a gradient based iterative algorithmare proposed. Anonlinear example is used to verify the effectiveness of the algorithms, and the simulation results show that the least-squares based iterative algorithmcan producemore accurate parameter estimates than the gradient based iterative algorithm.
