Reconfigurable Control Problem and Fault-Hiding Approaches by the reconfigured closed-loop system. First, reconfiguration problems are formulated based on model-matching ideas. Second, the fault-hiding concept is introduced and the reconfiguration problems are formulated in this context. The fault-hiding concept is the basis for all reconfigurable contro

Linear Reconfiguration Solutions Based on the Fault-Hiding Approach systems are defined, some of their basic properties are reviewed, and the nominal closed-loop system is defined. It is shown how faults are modelled in linear systems. The linear virtual sensor and the linear virtual actuator are defined, and it is described how they must be designed such that the

Setpoint Tracking Recovery after Actuator Faults in Saturated Systemsnfiguration solution to achieve tracking of constant setpoints. Feasible setpoints that can be reached by the faulty plant are characterised, and it is shown that a suitably designed saturated virtual actuator ensures that they be reached. It is furthermore shown how infeasible setpoints are mapped

Control Reconfiguration Problem for Piecewise Affine Systems about the nominal closed-loop system. It is shown how faults are modelled in piecewise affine systems, and the corresponding reconfiguration problems are formulated. The chapter closed with bibliographic notes.

Application Frameworkn flow between plant, controller, and reconfiguration block is described, and it is shown how reconfiguration blocks can be embedded into modern control hardware. A MATLAB toolbox providing prototype implementations of reconfiguration blocks is described. Finally, possible applications for virtual a

Fault-Tolerant Control of a Thermofluid Processthat has been realised on the test bed plant VERA. Closed-loop trajectories of the reconfigured process are discussed for various fault scenarios. They demonstrate that the approach is indeed suitable for solving reconfigurable control problems in practice.

Introduction to Reconfigurable Controlonly if the involved actuators and sensors function properly. Actuators and sensors are, however, subject to inevitable faults, and fault-tolerant controllers should nevertheless maintain the system’s main functionality. This monograph focusses on actuator and sensor faults.
