This paper describes techniques for the design of a system able to interact with the user by visual recognition of hand gestures. The system is composed of three modules including tracking, posture classii-cation and gesture recognition. A description of each module is given. In order to increase the robustness and the precision of the tracking, several complementary tracking processes are coup...

The tracking of objects and humans has recently received a lot of attention as a tool to improve business processes, occupational and public safety. In industrial environments wireless sensor networks can facilitate deployment of tracking applications as they can establish a standalone communication infrastructure (a so called mesh network). Many such positioning and location tracking systems d...

Abstract  A position control algorithm for a beltdriven servomechanism of a laser-cutting machine is described. High-accuracy position tracking control procedure for the system with inherent elasticity due to the low-cost belt-driven servomechanism is derived using sliding mode motion control strategy and Lyapunov design. The control design results in continuos sliding mode control law. It pos...

Abstract: A Fuzzy logic control law is presented and implemented for trajectory tracking of multiple under actuated autonomous surface vessels. In this study, an individual unmanned ship is used to be the leader that tracks the desired path; other unmanned ships are used to be the followers which track the leader only by using its position. A fuzzy controller was implemented for the ship leader...

There are actually several solutions for two axis solar tracking systems using electromechanical devices, in which a controller detects the Sun apparent position, and controls the position of the structure supporting the panels toward the sun by enabling the engines movement. This work studies the solution of two axis solar tracking system based on solar maps, which can predict the exact appare...

The three-dimensional CMKF-D with only position measurements is extended to solve the radar target tracking problem with range-rate measurements, where the errors between range and range-rate measurements are correlated. Firstly, a pseudo measurement is constructed by the product of range and range-rate measurements to reduce the high nonlinearity of the range-rate measurements with respect to ...

This paper is devoted to the study of consensus tracking problems for multi-agent systems with nonlinear dynamics, in which dynamics of each follower consists of two terms: one is given by an inherent nonlinear dynamics and the other is a simple communication protocol relying only on the position of its neighbors. The consensus reference is taken as a virtual leader who gives only its position ...

In ad hoc networks, node mobility causes the network topology to change dynamically over time, which complicates important tasks such as routing and flow control. We propose a distributed scheme for accurately and efficiently tracking the mobility of nodes in ad hoc networks. A first-order autoregressive model is used to represent the evolution of the mobility state of each node, which consists...

–A permanent magnet two phase AC servo motor is widely used for high performance position control applications. Nevertheless with the presence of nonlinearities, and the input is periodic, conventional type controller is not sufficient to provide satisfactory time-varying trajectory position control. In order to improve the tracking performance for periodic reference trajectory, this article pr...
