Iterative learning control for variable frequency drives
2008 IEEE Power Electronics Specialists Conference, 2008 Variable frequency drives (VFD) are subject to various types of disturbances especially cyclical ones. These periodic disturbances are difficult to compensate by conventional controllers. Repetitive control can only compensate for constant frequency fluctuations. PWM inverter based VFDs are subject to periodic disturbances with variable frequency.
