The propagation of periodic mechanical waves through the tissue can be captured by means of a modified phase contrast sequence. These waves are generated with a mechanical oscillator (actuator) and coupled into the tissue through the skin. The actuator must be capable of generating a sinusoidal excitation with excellent phase and amplitude stability, while not disturbing the MR imaging process. In this work, an actuator based on a piezoelectric principle was developed. Based on the imaging evaluation of several material samples, the housing for the piezoelectric ceramic was constructed of aluminum. Smaller parts of the housing were manufactured from brass and titanium to fulfill the mechanical constraints. A lever was used to transfer the oscillation generated by the piezoelectric ceramic to the point of excitation. The lever amplifies the piezoelectric motion, allowing for a more compact design. Three different lever designs were characterized by an acceleration sensor both outside and inside the magnet. It was shown that the rigidity of the lever, as determined by its material and form, was decisive in determining the resonant frequency of the system and therefore the maximum practical frequency of operation. It was also shown that the motion of the oscillator is unaffected by the electromagnetic fields of the MR imager. The final design can be placed directly in the magnet bore within a few centimeters of the tissue volume to be imaged without generating significant artifacts. An amplitude range of 0-1 mm in the frequency range from 0 to over 300 Hz was achieved, sufficient for performing most MR elastography applications. © 2002 Wiley Periodicals, Inc.

In this contribution a control concept based on Exact I/O-Linearization is proposed and compared to a conventional cascade control structure. In order to adapt the exact linearization control strategy to various polymerization products and batch conditions, an advanced probabilistic inference algorithm (Sigma-Point Kalman Filter) is applied and investigated. Sigma-Point Kalman Filters have the major improvement of simplified implementation compared to local linearization methods (i.e. Extended Kalman Filter) because no analytical Jacobians are required. Stochastic simulation studies are introduced and show the effectiveness, accuracy and benefit of the control concept. Within several scenarios a satisfying robustness against structural errors in the underlying model equations for the nonlinear control law and the inference algorithm is demonstrated. Furthermore it is pointed out, that with little effort in reassembling the plant design, control performance can be improved significantly.}, language = {en} } @phdthesis{Grote2009, author = {Grote, Wolfgang}, title = {Ein Beitrag zur modellbasierten Regelung von Entnahmedampfturbinen}, publisher = {Bochum}, organization = {Ruhr-Universit{\"a}t Bochum}, pages = {244}, year = {2009}, subject = {Dynamische Modellierung}, language = {de} } @inproceedings{GroteSchulzeDarupReinig2009, author = {Grote, Wolfgang and Schulze Darup, M. and Reinig, G.}, title = {Modellpr{\"a}diktive Regelung von Entnahmeturbinen und Dampfnetzen (Poster)}, series = {Chemie Ingenieur Technik}, volume = {2009}, booktitle = {Chemie Ingenieur Technik}, number = {8}, publisher = {Wiley}, address = {Weinheim}, doi = {10.1002/cite.200950184}, pages = {1113 -- 1114}, year = {2009}, language = {de} } @inproceedings{GroteReinig2009, author = {Grote, Wolfgang and Reinig, Gunter}, title = {Modellbasierte Regelung von Entnahmedampfturbinen (eingeladener Vortrag)}, series = {43.
