German Americans especially regarding pastries, meats and sausages, and above all, beer. Frankfurters (or "wieners", originating from Frankfurt am Main and Vienna, respectively), hamburgers, bratwurst, sauerkraut, and strudel are common dishes. German bakers introduced the pretzel, which is popular across the United States. Germans introduced America to lager, the most-produced beer style in the United States, and have been the dominant ethnic group in the beer industry since 1850. The oldest extant brewery in the United States is D. G. Yuengling & Son of Pottsville, Pennsylvania (approximately 80 miles northwest of Philadelphia), founded in 1829 by an immigrant from Aldingen in what
Linear parameter-varying control Linear parameter-varying control Linear parameter-varying control (LPV control) deals with the control of linear parameter-varying systems, a class of nonlinear systems which can be modelled as parametrized linear systems whose parameters change with their state. In designing feedback controllers for dynamical systems a variety of modern, multivariable controllers are used. In general, these controllers are often designed at various operating points using linearized models of the system dynamics and are scheduled as a function of a parameter or parameters for operation at intermediate conditions. It is an approach for the control of non-linear systems that uses a family of linear
