Chapter
Relay Feedback and its Variations
Suppose that a relay feedback system is stable and eventually yields limit cycles. The information contained in the limit cycles can be used for process frequency response estimation, as pioneered by Åström an...

Chapter
Use of Relay Transient Responses
In the preceding chapter, relay feedback has been employed to identify the process frequency response. It is, however, noted that the frequency response is obtained only at a few discrete frequency points. Ess...
