Modeling and Identification of Discrete-Time Nonlinear Dynamic Cascade Systems with Input Hysteresis

Abstract EN

A simple approach to modeling and identification of discrete-time nonlinear dynamic systems having an input hysteresis in cascade with a linear dynamic system is presented.

A special form of Coleman-Hodgdon model for the hysteresis is considered, which is linear in parameters.

For the cascade system parameter estimation, an iterative method with internal variable estimation is proposed.

Simulation studies of cascade systems identification using special periodic inputs are included.
