Discrete torque generation mechanism and inherently nonlinear magnetic characterization of switched reluctance motors lead to unacceptable torque ripple and reduce the variety of applications in industry. In this paper, a phase current profiling technique is proposed considering magnetic saturation effects as well as minimizing power loss during the commutation area between the adjacent phases. Constant...
Torque pulsation mechanism and highly nonlinear magnetic characterization of switched reluctance motors (SRM) lead to unfavorable torque ripple and reduce the variety of applications in industry. In this paper, a torque sharing function (TSF) is proposed considering magnetic saturation effects as well as minimizing power loss during the commutation region. Constant torque trajectories are considered...
In this paper we propose a system design for delivery of immersive communications to mobile wireless devices based on a distributed proxy model. It is demonstrated that this architecture addresses key technical challenges for the delivery of these services, that is, constraints on link capacity and power consumption in mobile devices. However, additional complexity is introduced with respect to mobility...
Multicasting of real-time streams (voice, video, etc.) for interactive communication in networked virtual environments (V.E.) is becoming an increasingly important service. Here as an example characteristics of interactive voice scenes for participants in a V.E. are presented. Proxy based overlay multicasting of real-time streams is a candidate architecture for this type of service. Here we propose...
This paper develops a scalable system design for the creation, and delivery over the Internet, of a realistic voice communication service for crowded virtual spaces. Examples of crowded spaces include virtual market places or battlefields in online games. A realistic crowded audio scene including spatial rendering of the voices of surrounding avatars is impractical to deliver over the Internet in...
