This paper proposes a novel method for sensor allocation based fault tolerant control. Fault tolerance is achieved with optimal combination of healthy sensor sources while the baseline controller remains unchanged. The measurements are subjected to various sensor dynamics, hence the resulting sensor allocation framework is also dynamic. The proposed approach can fit into a hierarchical fault tolerant control framework, where certain sensor faults are handled by the lower level allocation while
