Rotor current fuzzy control of a DFIG with an Indirect Matrix Converter

A review of predictive control techniques for matrix converters — Part I

“…The indirect matrix converter (IMC) shown in Fig. 4 is other topology where important contributions of predictive control have been done, such as reported in [20], [23], [25]- [29], [31], [36], [40], [44]- [46], [62]. The IMC, in contrast to the DMC, presents a more simple modulation and commutation known as zero dclink current strategy [3], [40], which allows to reduce the commutation losses and thus increase the efficiency of the converter.…”

“…But as only a positive dc-link voltage is allowed at any time, the number of valid switching states in the rectifier side that can be applied at any specific time are reduced to only three, thus, the total number of valid switching states that are evaluated in the cost function are reduced to twenty-four. Similarly to the DMC, predictive control in an IMC has been implemented for motor drives in military, aerospace and renewable energy applications where size and weight are relevant issues [25], [62]. Moreover the mitigation of resonances on the input filter due to perturbations of the AC source and due to the commutations of the switches has been considered [23], [26], [28], [31].…”

A predictive direct power control applied to the Doubly Fed Induction Generator under voltage dip

“…The benefits of using an indirect matrix converter (IMC) to the rotor current control by using MBPC and fuzzy logic control (FLC) are presented in [2], [3], respectively. A comparison of the simulation performance between these two papers is presented in [4], and the FLC presents a smaller mean and RMS error.…”
