Fault-Tolerant Process Control focuses on the development of general,
yet practical, methods for the design of advanced fault-tolerant control
systems; these ensure an efficient fault detection and a timely response
to enhance fault recovery, prevent faults from propagating or developing
into total failures, and reduce the risk of safety hazards. To this end,
methods are presented for the design of advanced fault-tolerant control
systems for chemical processes which explicitly deal with
actuator/controller failures and sensor faults and data losses.
Specifically, the book puts forward:
- A framework for detection, isolation and diagnosis of actuator and
sensor faults for nonlinear systems;
- Controller reconfiguration and safe-parking-based fault-handling
methodologies;
- Integrated-data- and model-based fault-detection and isolation and
fault-tolerant control methods;
- Methods for handling sensor faults and data losses; and
- Methods for monitoring the performance of low-level PID loops.
The methodologies proposed employ nonlinear systems analysis, Lyapunov
techniques, optimization, statistical methods and hybrid systems theory
and are predicated upon the idea of integrating fault-detection, local
feedback control, and supervisory control. The applicability and
performance of the methods are demonstrated through a number of chemical
process examples. Fault-Tolerant Process Control is a valuable
resource for academic researchers, industrial practitioners as well as
graduate students pursuing research in this area.
