Abstract :
A fault-tolerant repetitive control (FTRC) scheme is proposed for three-phase CVCF PWM inverters to improve system reliability and survivability against sensor fault. The proposed control architecture is made up of two layers. The advantage for separating it into two layers are that it provides a clear development structure, independent specification and development of each layer, and last but not the least, testability of detector and effector functions. Simulation results are provided to verify the effectiveness of the proposed scheme.
