__Short Desciption__:

This paper is focused on Fuzzy Extreme Learning Machine (ELM) algorithm based field oriented control system for induction motor fed by Matrix Converter drive.

__Summary__:

This paper is focused on Fuzzy Extreme Learning Machine (ELM) algorithm based field oriented control
system for induction motor fed by Matrix Converter drive. The use of fuzzy ELM algorithm based ANN
Controllers in the FOC system reduces the computation time. The controller is used to compute the
appropriate set of switching voltage vectors for matrix converter to achieve the maximum efficiency for
any value of operating torque and motor speed. In this paper, the Matrix Converter with field oriented
control system is designed using MATLAB/SIMULINK toolbox. Initially, fuzzy logic controllers are used
as current and torque controllers. ELM controller is designed to replace space vector modulation circuit in
the conventional field oriented control system. The three inputs to the Fuzzy ELM controller are Va
*, Vb
*
and Vc
* and the outputs of the ELM controller are voltage vectors for appropriate switching of matrix
converter. The performance of the induction motor is tested for various reference speed and torque values.
The speed and torque curves of the induction motor shows that the use of ELM controller reduces the
ripples in torque and reduces the response time in the speed curve due to the fast response time of the ELM
Controller
Keywords:Matrix Converter, Fuzzy logic Controllers, Extreme Learning Machine Algorithm, Field
