Direct Torque and Indirect Flux Control of BLDC Motor Controller by Using Fuzzy Logic Controller

Abstract

In the present scenario, utilization of BLDC drives are increasing rapidly, as a result of more efficiency, more power density, normal to control and great inertia torque ratio. This rag proposes a concept of sensorless control of drive using Fuzzy based DTC system. An indirect flux control proposed in this rag is similar to the direct torque controller for controlling of BLDC motor by the reference signals from the direct axis currents. A fuzzy regulator also proposed in this rag for better controlling of brushless DC drive. Simulink/Matlab is used to test the proposed DTC-Fuzzy based BLDC drive
