Direct Torque Control of Induction Drive Using Fuzzy Controller

Abstract

In this study the direct torque control of the induction drive with a fuzzy controller was investigated. The objective of this research was the reduction of the stator current and electromagnetic torque pulsations. The principles of the fuzzy controller development for the induction drive with a direct torque control and the obtained computer model were presented, and the simulation results were compared to the results of the induction drive under the traditional direct torque control. The implementation of the applied fuzzy controller allowed us to achieve the pulsations of the torque twice lower, the stator current, flux and the maximum overshoots were lowered.

Survey on Neuro-Fuzzy Based Single Phase Multi-Level Inverters Using FPGA

“…The DSP processor here used as a coprocessor in AC-voltage regulation [3]. The Neural networks based SVM for different levels of inverters is designed and implemented using hardware, these NN are independent of switching frequencies [4]. The NFC and FPGA controller used in the implementation of 5 level inverter or PWM inverters, in which the modulation index is was selected by calculating the required DCbus voltage of a active filter through a digital controller.…”

Design of ramp-time current control with dynamic fuzzy bandwidth for wireless power transmission

“…The optimal current control can accurately follow the reference current with ZACE in each switching period. Ramp-time current control was applied to determine the ZACE approach with fixed switching frequency [22, 23]. This approach uses stand-alone current error signals to obtain switching instants and maintain a narrow switching frequency band.…”
