the direct torque control (dtc) of interior permanent magnet synchronous motor (ipmsm) offers simple structure and fast torque response. the conventional switching table-based dtc (st-dtc) presents some disadvantages like high torque and flux ripple and also variable switching frequency. this paper investigates the improved st-dtc strategies to reduce both torque and flux ripple in dtc of ipmsm...

Multichannel multiradio wireless networks allow one to utilize the available spectrum more efficiently to improve network performance. When nodes operate with multiple channels, the contention among the nodes operating in a particular channel is reduced, which translates to more opportunities to transmit and consequently improved throughput. Among the architectures proposed to implement a multi...

The unavoidable nonidealities with switching delay in current-mode-controlled buck converters have been reported in the literature. Investigations are carried out on the dynamical mechanism and its experimental validation on an interrupted circuit with switching delay. Switching delay is seen to influence a region of a two-valued function on a discrete map, and to induce the coexistence of a pe...

Need for high speed internet connectivity has lead to a substantial research in switching systems. Buffered crossbar switches have received a lot of attention from both research and industrial communities due of its flexibility and scalability. Designing a scheduling algorithm for buffered crossbar switches without starvation is a major challenge as of now. In this paper, we proposed a Delay ba...
