This paper provides a tutorial introduction to reconfi-gurable control and surveys recent advances on this topic. Control reconfiguration is an important method of fault-tolerant control that uses the results of a fault diagnosis component to restructure the control loop and to adapt the controller to the faulty plant. This paper describes recent approaches(More)
A reconfigurable control approach for continuous-time piecewise affine (PWA) systems subject to actuator and sensor faults is presented. The approach extends the concept of virtual actuators and virtual sensors from linear to PWA systems on the basis of the fault-hiding principle that provides the underlying conceptual idea: the fault is hidden from the(More)
The increase in complexity in process control goes along with an increasing need for complete and guaranteed fault diagnosis. In this contribution, we propose a set-based method for complete fault diagnosis for polynomial systems. It is based on a reformulation of the diagnosis problem as a nonlinear feasibility problem, which is subsequently relaxed into a(More)
—This paper presents our multi-year experience in the development of a Functional Modeling Compiler (FMC), a new model-based design tool for the development of multidisciplinary automotive cyber-physical systems. We show how system-level simulation models suitable for design-space exploration of complex architectures can be synthesized from functional(More)
— A new approach to the reconfigurable control of piecewise affine (PWA) systems after actuator and sensor faults is presented. The approach extends the concept of virtual actuators and virtual sensors from linear to PWA systems on the basis of the fault-hiding principle. The weak fault-hiding goal is introduced as a relaxation of the asymptotic(More)
This report surveys recent results and approaches from the field of control reconfiguration within a general fault-tolerant control framework. Open problems for future research are identified. Control reconfiguration is embedded within a wider fault-tolerant control context and set apart from other approaches to achieve fault tolerance. It is explained why(More)
