Robustness Evaluation of Fuzzy Logic Control Based on Feedback Linearization of Induction Motor Fed by Matrix Converter

Abstract

In this paper, The input-output feedback linearization technique is used with a fuzzy logic controller to generate the reference voltages for a MC controlled by direct space vector modulation strategy, to achieve a high performance and to ensure a robustness with respect to variations of reference values of speed, torque, and rotor flux on the one hand, and on the other hand to obtain an operation without injecting harmonics into the grid. Moreover, this paper deals with the damped input filter design of matrix converter. The transfer function and the optimized parameter selection approach of the input filter are also introduced. Finally, in order to examine the effectiveness of the suggested control approach for the drive system considered, a simulation study was carried out.
