This paper presents a distributed fault-tolerant finite-time control scheme for the secondary voltage and frequency restoration of islanded inverter-based Alternating Current (AC) Microgrids (MGs) considering input saturation and faults. Most existing distributed methods commonly design the secondary control layer based on ideal conditions of the control input channels of the MG without any faults and disturbances. At the same time, MGs are exposed to actuator faults that can significantly impact the control of MGs, and lead the MG in unstable situations. One of the other typical practical constraints in multi-agent systems such as MGs is saturation. The other novel idea is that a consensus-based scheme synchronizes the islanded MG’s voltage and frequency to their nominal values for all DGs within finite time, irrespective of saturation and multiple faults, including partial loss of effectiveness and stuck faults simultaneously. Finally, the performance of the proposed control schemes are verified by performing an offline digital time-domain simulation on a test MG system through a couple of scenarios in MATLAB/Simulink environment. The effectiveness and accuracy of the proposed control schemes for islanded AC MGs are compared to previous studies, illustrating the privilege of that.
