Identification of block oriented nonlinear models using relay

Abstract

Relay feedback identification technique is widely used in process control industries but its application is limited mainly to linear systems This thesis focuses on extending the applicability of relay feedback to nonlinear system identification For the said purpose two nonlinear models have been studied the Wiener and the Hammerstein model Requirements of many tests and sometimes a complete change of set up have been reported in the literature This thesis work tries to resolve these issue...
