This research monograph summarizes solutions to reconfigurable
fault-tolerant control problems for nonlinear dynamical systems that are
based on the fault-hiding principle. It emphasizes but is not limited to
complete actuator and sensor failures. In the first part, the monograph
starts with a broad introduction of the control reconfiguration problems
and objectives as well as summaries and explanations of solutions for
linear dynamical systems. The solution is always a reconfiguration
block, which consists of linear virtual actuators in the case of
actuator faults and linear virtual sensors in the case of sensor faults.
The main advantage of the fault-hiding concept is the reusability of the
nominal controller, which remains in the loop as an active system while
the virtual actuator and sensor adapt the control input and the measured
output to the fault scenario. The second and third parts extend virtual
actuators and virtual sensors towards the classes of Hammerstein-Wiener
systems and piecewise affine systems. The main analyses concern
stability recovery, setpoint tracking recovery, and performance recovery
as reconfiguration objectives. The fourth part concludes the monograph
with descriptions of practical implementations and case studies. The
book is primarily intended for active researchers and practicing
engineers in the field of fault-tolerant control. Due to many running
examples it is also suitable for interested graduate students.
