“…Equation (5) shows that the tracking properties can independently be designed from the regulating behavior by Q r . The last scheme was later named as a generic two-degree of freedom (G2DF) system [1], [2]. The K-B parameterization for closed-loop control is not so widely known as the Youla-Kucera-(Y-K) parameterization [4] however, it is much closer to a control engineering view and its most important advantage in 2DF systems is that it virtually opens the closed-loop.…”

“…It was shown [1], [2] that the optimization of the G2DF scheme can be performed in H 2 and H ∞ norm spaces by the proper selection of the serial and embedded filters (compensators). These optimizations are reduced to the optimal computation of the G r and embedded filters.…”

The paper discusses some interesting, mainly philosophical paradigms of the modeling and control areas, which are still partly unsolved and/or only partially studied. First the possible introduction of a prejudice free controlsimilar to the term for the modeling introduced by Rudi Kalman -is investigated. Next the real constraints in real control systems are discussed. It seems that these are the amplitude limit for the actuators in practical systems. Then the application of the HEISENBERG-type uncertainty relationship in control is discussed, combining the robustness of control and quality of modeling. Finally a special irregularity in the classical LQR control methodology is treated investing some unreachable poles in the anomaly. The paper constitutes a review of a few specific problems in the control theory. They are enumerated in keywords and discussed on the basis of the references. The authors aim at least to invite further authors to continue such a discussion.
