MARTINEZ-TORRES, César et al. Flatness-based fault tolerant control. Dyna rev.fac.nac.minas [online]. 2014, vol.81, n.188, pp.131-138. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v81n188.41275.

This paper presents a Fault Tolerant control approach for nonlinear flat systems. Flatness property affords analytical redundancy and permit to compute the states and control inputs of the system. Residual signals are computed by comparing real measures and the computed signals obtained using the differentially flat equations. Multiplicative and additive faults can be handled indistinctly. The redundant signals obtained with the differentially flat equations are used to reconfigure the faulty system. Feasibility of this approach is verified for additive faults in a three tank system.

Keywords : Fault tolerance; differential flatness; three tank system.
