This paper deals with an analytical approach based on the inverse dynamic model to maintain the stability of the ROBIAN robot in the presence of external disturbances. The stabilization is carried out with a trunk having 4 degrees of freedom: three translations and one rotation. For a vertical posture of the robot, the trunk bodies of ROBIAN are used to compensate the external three-dimensional efforts...
Location of the static VAR compensator (SVC) and other types of FACTS devices is important for the enhancement of practical power systems voltage stability. In this paper, a Multi-objective particle swarm optimization (MOPSO) is used to solve a mixed continuous-discrete multi-objective optimization problem in order to find optimal location of FACTS. Various objectives are considered, namely voltage...
This paper investigates stability of a drive system incorporating a high-field PM synchronous motor with the aim of identifying a real-time stability index by means of an algorithm based on the Lyapunov method. Results from computer simulation show that the first principal minor (MINR1) of the Lyapunov function has a distinct sign change in the region of interest. Such an important finding makes it...
Segmentation is a fundamental stage in image processing since it conditions the quality of interpretation. Fusion in remote sensing has one goal which is to combine different images obtained by different sensors in one image or in different images in order to improve the content and the resolution of these images. In this research, a new fusion method is implemented to improve the segmentation process...
The analytical expression of a fuzzy controller has been studied when the output fuzzy membership functions are equally spaced and triangular or trapezoidal. The cases, when a fuzzy set of the output is extreme - with respect to the universe of discourse - or not extreme have been considered. When considering extreme sets, the controller can be approximated with a good precision by a second-degree...
