Fuzzy logic based matrix converter controlled indution motor drive

In terms of efficiency, lifetime, compactness and unity power factor operation, the matrix converter is far better than the conventional converter. The conventional control topology based converter is not suitable for efficient speed control of induction motor by direct torque control system. The fuzzy controller based matrix converter can be a suitable option for efficient speed control of induction motor by direct torque mechanism. The mathematical model of switching algorithm of matrix converter as well as power and fuzzy logic controller are designed by modified venturini algorithm and mandani rule. The performance of the proposed fuzzy controller based matrix converter drive is first evaluated by simulated model by using Matlab Simulink. A laboratory setup comprising of DSP and FPGA control based matrix converter drive is used to validate the simulation results of the simulated model. From both simulated and experimental results, the efficient and stable control of torque of induction motor with distortion less output current and less THD (total harmonic distortion) in output voltage can be obtained.
