FD problem for HS has attracted some attentions. However, to the best of the authors knowledge, until now, the FTC issue for HS has not yet been intensively studied. FTC method for HS deserves further investigations due to its academic meaningaswellaspracticalone. 1.

The HS considered in this book consists of a series of continuous modes and a switching logic. Switching from one mode to another is due to a switching law generated from the switching logic. Faulty behaviors of HS are investigated s- tematically.Two main kindsof faults are considered:Continuous faults that affect continuous modes; Discrete faults that affect the desired switching.

Rezensionen

From the reviews:
"Fault detection and fault tolerant control techniques have received wide attention in the field of continuous-time, especially linear, systems. ... Hence the monograph in question is a very suitable addition to this field. ... There is a list of references, with 157 entries, which is a very good compendium of the literature in the field. On the whole, this monograph is a good addition to the industry-relevant research in the field of fault detection and fault tolerant control." (Amit Patra, Mathematical Reviews, Issue 2011 e)
