Motion planning in dynamic environments consists of the generation of a collision-free trajectory from an initial to a goal state. When the environment contains uncertainty, preventing a perfect predictive model of its dynamics, a robot ends up only successfully executing a short part of the plan and then requires replanning, using the latest observed state of the environment. Each such replann...

An accurate average value model of synchronous machine-rectifier system considering the effect of stator resistance is derived in this paper. A proper voltage-behind-reactance synchronous machine model without any approximations is used for the generator that allows effective calculation of commutation displacement angle. All rectification modes of the rectifier are studied. A detailed switchin...

On April 6, 2009, an earthquake of 6.3 magnitude struck central Italy with its epicentre near L'Aquila, at 42.3502° N, 13.3762°E. The earthquake damaged 3,000 to 11,000 buildings in the medieval city of L'Aquila. Several buildings totally collapsed, 308 people were killed. The post emergency phase till now is just at its beginning step. Conventional surveying techniques using high precision tot...

Accurate load power sharing and bus voltage regulation are two critical control objectives for ensuring quality reliable operation of DC microgrids. Although regulating the Bus can be achieved by adopting an external secondary loop, inaccurate power/current among converters is a prominent issue due to feeder resistances mismatch. This lead undesired overloading converters, triggering over-curre...

This paper presents an accurate machining feedrate prediction technique by modeling the trajectory generation behaviour of modern CNC machine tools. Typically, CAM systems simulate machines motion based on commanded and path geometry. Such approach does not consider feed planning interpolation strategy numerical control (NC) system. In this study, NC system is modelled cycle time for complex to...

. This paper describes a simulation tool developed for 3G planning and suitable also for some RRM strategies evaluation. The innovative issue is that the simulator is based on data extracted from real GSM/UMTS networks. Considering the extensive use of GSM/UMTS co-siting for 3G network deployment, an accurate representation of propagation, mobility as well as traffic distribution is achieved co...

Accurate models for electric power load forecasting are essential to the operation and planning of a power utility company. Load forecasting helps electric utility to make important decisions on trading of power, load switching, and infrastructure development. Load forecasts are extremely important for power utilizes ISOs, financial institutions, and other stakeholder of power sector. Short ter...

It is important to minimize the energy consumption of autonomous ground vehicles (AGVs) deployed in real world missions. One of the ways that this can be accomplished is to choose the vehicle’s motion to minimize the mechanical and electrical energy usage required by the vehicle’s motion. This paper considers energy efficient motion planning for skid-steered AGVs, an important and large class o...
