An optimal nonlinear system identifier based on quasilinearization

Abstract

Identification techniques which use quasilinearization as a basis are among the fastest converging, however, they often suffer from having a narrow region of convergence when applied to nonlinear systems. An identification process, based on quasilinearization, will be presented which has a larger region of convergence than other, similar methods. This identification process will be demonstrated and compared with similar methods in an example using the Van der Pol equation.
