After testing many different designs, we built a rough orientation control system using a 3-axis accelerometer, able to sense and direct mirror orientation with close to one degree of precision (20 milliradians) for the entire motion range of the mirror. This level of precision is required for orientation tasks such as stowing the mirror in high winds and bringing the light spot close enough to...

Virtual Reality, Interaktion und stereoskopische Projektion sind die Bereiche des VRLab der Hochschule Reutlingen. Diese werden in mehreren Teilprojekten bearbeitet, von denen hier die „Remote Control“, das „Low-cost Tracking System“ und das „3D-Modellhandbuch“ vorgestellt werden.

This paper is devoted to a unified approach to trajectory tracking control of nonholonomic port-controlled Hamiltonian systems via generalized canonical transformations. The key idea is to construct an error system, which describes the dynamics of the tracking error, by a passive port-controlled Hamiltonian system. This strategy works for both holonomic and nonholonomic port-controlled Hamilton...

The main objective of design methodology of a controller for forecasting cardiac arrest using fuzzy logic approach is to provide the prediction of period of life time for the patients affected by sudden death due to cardiac arrest. In this paper, the controllable risk factors “blood pressure, cholesterol, diabetic, obesity” are taken as inputs for the fuzzy logic controller and “the period of l...

multiple people detection and tracking is a challenging task in real-world crowded scenes. in this paper, we have presented an online multiple people tracking-by-detection approach with a single camera. we have detected objects with deformable part models and a visual background extractor. in the tracking phase we have used a combination of support vector machine (svm) person-specific classifie...

control of robotic systems is an interesting subject due to their wide spectrum applications in medicine, aerospace and other industries. this paper proposes a novel continuous control mechanism for tracking problem of a 5-dof upper-limb exoskeleton robot. the proposed method is a combination of a recently developed robust integral of the sign of the error (rise) feedback and neural network (nn...

In this study, to achieve high trajectory tracking performance in electro-optical systems under strong nonlinear disturbances and uncertainties, we develop a extended state observer (ESO) based fractional-order sliding mode control. When compared with previous work, the new compound control strategy is attractive terms of following three points. First, novel controller developed that integrates...

In this paper, we propose a new tracking system based on a stochastic filtering framework for reliably estimating the 3D pose of a user’s head in real-time. Our system estimates the pose of a user’s head in each image frame whose 3D model is automatically obtained at an initialization step. In particular, our estimation method is designed to control the diffusion factor of a motion model adapti...
