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 EN

The identification of a class of linear-in-parameters multiple-input single-output systems is considered.

By using the iterative search, a least-squares based iterative algorithm and a gradient based iterative algorithm are proposed.

A nonlinear example is used to verify the effectiveness of the algorithms, and the simulation results show that the least-squares based iterative algorithm can produce more accurate parameter estimates than the gradient based iterative algorithm.
