Sumario:This paper presents a Fault Tolerant control approach for nonli near flat systems. Flatness property affords analytical redunda ncy and permit to compute the states and control inputs of the system. Residual signals are computed by comparing real measures and th e computed signals obtained using the differentially flat equatio ns. Multiplicative and additive faults can be handled indistinc tly. The redundant signals obtained with the differentially flat equatio ns are used to reconfigure the faulty system. Feasibility of th is approach is verified for additive faults in a three tank system.
