Aiming at the cooperative control problem of satellites formation flying with mass, inertia uncertainties and external disturbances, an adaptive cooperative control method is proposed. After the virtual structure mode is given, the position and attitude adaptive cooperative controllers of formation satellites and virtual structure are designed. Then, the system stability and the controllers' bounded...
A major drawback of evolutionary optimization approaches in the literature is the apparent lack of automated knowledge transfers and reuse across problems. Particularly, evolutionary optimization methods generally start a search from scratch or ground zero state, independent of how similar the given new problem of interest is to those optimized previously. In this paper, we present a study on the...
Distribution grid will be impacted to some extent when large scale electric vehicles (EV) are discharging simultaneously. Firstly, the factors related to the discharging power of EVs are discussed. Secondly, the probability density statistic models of discharging time and discharging duration are built according to the traffic pattern of X city in China and the national household travel survey of...
This paper presents a novel method for electric vehicle charging station planning based on weighted Voronoi diagram. First, the traffic flow of each intersection node is used to represent the road network traffic. The number of charging stations is estimated in accordance with the capacity of conventional-standard charging station. The initial locations are determined by using coordinate method. Then,...
The paper proposed a method of locating and sizing of charging station for electric vehicle based on grid partition. This method is aimed at minimizing the users' loss on the way to the charging station, zoning the planning area with grid partition method, and choosing the best location of each partition in GA (Genetic Algorithm) on the consideration of traffic density and charging station's capacity...
