A Switching Fault-Hiding Mechanism based on Virtual Actuators and Dwell-Time Conditions

Abstract : The design of an active Fault Tolerant Control (FTC) strategy based on Virtual Actuators (VA) and switching control theory is addressed. More precisely, a bank of VA is introduced between the baseline controller and the plant to hide and accommodate the fault. If the proposed solution possesses the advantage to maintain the baseline – and potentially certified – controller, it is also assumed here to keep the analytical diagnosis filters – potentially certified too – that monitor the plant. The problem is next formulated in the context of supervisory control where the cases of intermittent and abrupt faults can be covered. It is shown how a separation principle can be found to guarantee the closed loop stability of the overall switching system by using dwell-time conditions. Finally, the proposed solution is applied to the HiMAT benchmark.
