Mauro Riva - Two observers for joint parameter and state estimation are presented in this paper.
In this paper a fully integrated Data Analytics Infrastructure is introduced, which is applicable for different use-cases. State estimators are used to reconstruct current plant states based on information received from plant sensors and the use of a mathematical model. The typically applied Kalman filter derivatives require knowledge about the noise statistics affecting system states and measurements. These are often unknown and inaccurate parameterization may lead to decreased filter performance or even filter divergence. In this paper, a comparison between two covariance estimation methods is presented. Both methods are evaluated in simulations and experiments using a pendubot w. The results show that with both methods the filter performance can remarkably be improved. In this paper a comparison of three methods for online parameter estimation is presented. The methods' performances regarding accuracy, respond time and computing time are compared using a commercial industrial testbed, consisting of a linear belt drive for positioning tasks, an industrial servo inverter and a programmable logic controller. In addition, the online state sensitivity w. These signals can be used to stop the parameter estimation for insufficient excitation. Two observers for joint parameter and state estimation are presented in this paper. Sensitivity models are introduced to compute and minimize a cost functional and then recursively estimate parameter and process covariance values online. The algorithm performance is tested using simulation models of two test benches. We focus on similarity measures that are common in this field, e. Matching is realized considering appropriate image pre-processing, the aforementioned similarity measures, and local optimization algorithms, as well as line search optimization. For evaluation purpose, the results of a point-based registration with fiducial landmarks are regarded as ground truth. First results indicate that state of the art similarity functions do not perform with the desired accuracy, when applied to unprocessed image data. The choice of a navigation system highly depends on the medical intervention and its accuracy demands. We simulate a robotic assisted surgical intervention, including planning, navigation, and processing, and compare the accuracies reached at a specific target with each navigation system. These observers are compared in terms of convergence and response time riva hannover erroneous parameter and state initialization, as well as parameter modifications during operation. Designing a Kalman filter requires knowledge about riva hannover stochastic part of the system. Thus, disturbances affecting states and measurements should be known. However, in practical application these disturbances are usually unknown. In this contribution a modification of the autocovariance least-square method is presented. This method converts the measurement and process noise covariance estimation problem into a least squares functional, which can be solved with a Landweber iteration to regularize the ill-posed problem. Then, a tuned Kalman filter gain can be calculated. A simulative evaluation is introduced to prove the method regarding robustness against modeling error and variance of the estimates. In this paper a multi-axial electromagnetically actuated punch is presented. This punch can apply forces up to 60 kN and has a maximum stroke of 4 mm. Especially, the punch is qualified for manufacturing micro-components demanding high accuracy and high stroke rates. Due to its multi-axial drive concept, the punch is able to compensate the tilt of the ram during the cutting process. Thus, abrasion at the die is reduced and the punching quality is improved. Therefore, two multiaxial control concepts are introduced and compared based on experimental results. An riva hannover Leibniz Universität Hannover wurden zwei elektromagnetische Stanzautomaten entwickelt. Bei diesen mittels Hochleistungselektro-magneten angetriebenen Pressen lässt sich die Stößelkinematik bis zu einer Hubzahl von 1600 Hub pro Minute riva hannover programmieren. Die neuartige Presse eignet sich vor allem zum Stanzen kleiner Bauteile, da aufgrund der kompakten Bauweise eine sehr hohe Genauigkeit er-reicht wird. Des Weiteren wurde ein servoelektrischer Walzenvorschub gebaut. Der Vorschub erlaubt eine genaue und sichere Positionierung des Blechs während des Betriebs der Pressen. At the Leibniz University of Hanover two metal forming machines were developed. These presses are driven by high-performance electro - magnets. Therefore, the kinematics of the ram can be programmed by the operator of the press as the ram is not rigidly connected to an eccentric shaft like at conventional presses. With these presses small components were manufactured accurately up to a stroke rate of 1,600 spm. Furthermore, a servo-electrically driven feeder was developed. This riva hannover accurately positions the sheet metal while the electromagnetically actuated press is in operation.

Packaging should be the same as what is available in a retail store, unless the item was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Thus, disturbances affecting states and measurements should be known.
