The task is further complicated by the imprecise dynamic model of the cart available and the unknown external disturbances. In the suggested solution a local optimization is applied by the use of which the appearance of the Riccati equations can be avoided. The adaptive controller is designed by the methodology based on the application of "Robust Fixed Point Transformations (RFPT)" that allows the separation of the kinematic formulation of the desired trajectory tracking behavior and its dynamic realization. It is shown via simulations that the purely kinematically formulated tracking compromise and the novel adaptive control design can successfully cooperate.}, year = {2014}, pages = {1-20}, orcid-numbers = {Kósi, Krisztián/0000-0002-5599-6277; Haidegger, Tamás/0000-0003-1402-1139} }
