Fuzzy Controllers based DTC of 6/4 SRM drive with Novel Converter

Abstract

Switched Reluctance Motor (SRM) is one of the best alternative motor drives for induction and synchronous drives in present trends. However, the SRM can able to replace those synchronous and inductance machine by using effective controller for many applications. Apart from many controllers, Direct Torque Controller (DTC) has received much attention from researchers in these days due to its high superiority characteristics over other controllers. Moreover, compare to Proportional and Integral (PI) controller a Fuzzy controller can provide effective support to DTC during intermittent changes of speed and torque. Hence, Fuzzy controller based DTC has been implemented in this paper for novel configuration of converter to drive SRM. Generally more number of switches leads to more cost and poor performance. Therefore, a novel configuration of converter has been proposed in this paper for DTC of SRM. For analysis of system, the proposed method has been compared with vector based controller in this paper. The extensive results are presented to validate the proposed method for both the steady state and transient periods.
