Actuators Additive Fault-Tolerant Control for Combat Aircraft

Abstract

As the decision-making process is crucial for Fault-Tolerant Control Laws, its design requires both significant attention and time. Indeed, if a wrong decision is made, there is generally no chance that the expected performance is achieved or that the system remains stable. The architecture proposed in this paper circumvents the decision-making problem by directly injecting an additional control law to the nominal one in order to compensate for the effect of the fault. Then, as the first step of a more general research project, the methodology is implemented and tested on the longitudinal linear model of a modern combat aircraft with different fault scenarios. Finally, simulation results show encouraging outcomes to compensate for the different actuator failures.
