Information dissemination control is of crucial importance to facilitate reliable and efficient data delivery, especially in networks consisting of time-varying links or heterogeneous links. Since the abstraction of information dissemination much resembles the spread of epidemics, epidemic models are utilized to characterize the collective dynamics of information dissemination over networks. From...
Islanding detection (ID) is a mandatory function for PV grid-connected converters. The traditional Sandia frequency shift method for ID becomes ineffective under certain parallel RLC loads. To alleviate this problem, a new methodology to optimize the frequency shift parameter Ks is proposed, and a novel non-detection zone (NDZ) mapping method is presented to map the NDZ influenced by each electrical...
A model reference robust repetitive control (MRRRC) scheme which integrates repetitive control with model reference robust feedback control is proposed for three-phase CVCF PWM inverters. The proposed scheme inherits their advantages from robust feedback control and repetitive control (RC): fast dynamic response, good robustness and high accuracy. MRRRC controlled inverter produces high quality output...
Hybrid-excited flux-switching (HEFS) machine is a relatively novel brushless machine having magnets, armature windings and field windings in the stator, as well as a simple and robust rotor. In this paper, the control strategies for the proper injection of field currents are proposed and implemented by a simulated model based on Matlab/Simulink. The predicted performance confirms the excellent flux-regulation...
