in this paper, a new control approach is proposed using adaptive integral backstepping controller (AIBC) for controlling an autonomous rotorcraft. The recursive Lyapunov methodology in the backstepping technique will ensure the system stability, the integral action will increase the system robustness against disturbances and model uncertainties, and the adaptation law will estimate the modeling errors...
Overhead gantry crane systems have been integral part of many heavy industrial applications needing material handling and transportation. This can easily be seen in emerging countries growing rapidly. Single force control input applied to crane moves it to a desired position but also triggers undesired swing on the payload which makes it an interesting control problem for this underactuated system...
The degradation of signals and images can be caused by both natural perturbations and electronic systems, recording linear systems, in which parameters are slowly time-varying such as sensors or other systems of storage. Treatment of the above mentioned systems are discussed. For this purpose, Sekko & al. developed a structure, which is improved later by Neveux, in order to produce an inverse...
In this paper the design of an optimal nonlinear Hinfin (NL-Hinfin) controller for flexible joint robot (FJR) with bounded input control and fast tracking is presented. Moreover, FJR robot link positions are controlled without any undershoot and overshoot. Also, this paper discusses the robust L2-gain performance synthesis problem for uncertain FJRs which have nonlinear dynamic. So, the Hamilton-Jacobi...
The aim of this paper is to develop efficient, robust and automated image frame fusion algorithms for mosaicing and super-resolution. Image registration is the key step in combining multiple independent low-resolution images to give one large mosaic image with high resolution. Our research is based on Scale Invariant Features Transform (SIFT detector/descriptor) for geometric and photometric images...
In this paper, we present a framework for 3D visual odometry applied to a hospital-use transfer robot equipped with an omni-drive system. The approach is based on features extracted out of and matched in monocular image sequences. We propose a new feature detection and tracking scheme robust to motion blur and well suitable in environment, as a hospital, where the local features are sparse and not...
In this paper, we investigate the problem of designing Hfrinfin filter for a class of linear descriptor systems which can be realized in practice. It is established that the solution to the filtering problem can be cast in the format of linear matrix inequalities (LMIs). An important special cases is provided. A numerical example is worked out to illustrate the theoretical developments.
