摘要：AbstractThe 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 ofintermittentandabruptfaults 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 usingdwell-timeconditions. Finally, the proposed solution is applied to theHiMATbenchmark.
