Recursive Estimation from Relay Feedback Experiments

Recursive Estimation from Relay Feedback Experiments 

This chapter describes two new methods for obtaining frequency response and step response models from processes operating under relay feedback control. Both methods are based on the frequency sampling filter model structure and a recursive least squares estimator. 

This chapter contains three sections. Section 8.2 describes the approach to frequency response estimation using data generated from a standard relay experiment. In Section 8.3, a modified relay experiment is proposed for step response estimation.
