Digitally controlled system has been widely used for the multi-inverter systems. However, the effects of time delay have not been fully studied in the grid-connected large-scale photovoltaic (LSPV) systems. To address this issue, this paper develops the general Norton model for grid-connected LSPV models by adding delay module into the inverter control system model. Meanwhile, based on the model of...
In recent years, one of the hottest research topics is router buffer sizing. It is very important to size the buffer for routers with very small buffers in future Internet, in particular, in emerging optical networks as optical buffers are needed but very expensive. In 2004, the Stanford research group presented that the core router buffer needs only dozens of packets to meet acceptable link utilization...
In recent years, the router buffer sizing has become one of the hot research topics and researchers have been debating the size of buffers required at core Internet routers. It is very important to size the buffer for routers with very small buffers in future Internet, in particular, in emerging optical networks as optical buffers are needed but very expensive. In the year of 2004, the Stanford research...
Soft actuation materials, such as ionic polymer-metal composites (IPMCs), are gaining increasing interest in robotic applications since they lead to compact and biomimetic designs. In this paper, we propose the use of soft actuation materials as active joints for propelling biomimetic robotic fish. An analytical model is developed to compute the thrust force generated by a two-link tail and the resulting...
