Unfalsification based Fault Tolerant Controller

Unfalsified Control is a data-driven, plant-mo del-free control design approach. It does not require a plant model, only measured input/output data is used, which makes it an interesting approach for the development of multi-controller structures aimed either to the control of non-linear or time-varying processes, or the implementation of Fault Tolerant Controllers. In this paper, we present an Unfalsified Control based multi-controller structure for single-input single-output (SISO) plants. It includes a switching scheme designed without explicit assumptions on the plant model. A switched multi-controller structure is implemented and experimental results are presented. The switched multi-controller structure described shows to present good performance and fast reaction to modifications on the operating conditions.
