Trajectory tracking control for robot manipulators with no velocity measurement using semi-globally and globally asymptotically stable velocity observers

During the last decade the class of rigid robot systems has been the subject of intensive research in the field of systems and control theory, particularly owing to the inherent nonlinear nature of rigid robots. For the same reason, these systems have widely been used to exemplify general concepts in nonlinear control theory. As a result of this excessive research activity a large variety of co...

Stable Target Tracking using Observer Based Velocity Estimation

In applications where mobile robots are used to track non-cooperative moving objects it is often required that not only the position but also the velocity of the moving target can be measured. In this paper, we consider a problem in 2D where the tracking robots are equipped only with vision and position sensors and are unable to measure target velocity directly. Instead, two separate observers ...

Sound velocity measurement using transfer function method

Abstract The transfer function of a piezoelectric transducer, buffer rod and sample assembly is used to measure the sound velocity of solid materials. From the recorded transfer function, pulse echo patterns at frequencies of the passband of the input signal are reproduced after convoluting with monochromatic RF input signals. The time delay is obtained by performing pulse echo overlap and phas...

Velocity Estimation Using Semi-local Features

Computing the velocity field, or motion estimation is one of the most important issues in computer vision. And it is widely used in the areas of navigation, visual surveillance, video database, etc. . This problem has received a great deal of attentions over the last few years. This paper proposed a novel affine invariant feature set which localization ability is adjustable . And based on this ...

Velocity estimation using synthetic aperture imaging

In a previous paper we have demonstrated that the velocity can be estimated for a plug flow using recursive ultrasound imaging [1]. The approach involved the estimation of the velocity at every emission and using the estimates for motion compensation. An error in the estimates, however, would lead to an error in the compensation further increasing the error in the estimates. In this paper the a...
