This paper considers the global practical output tracking problem by at least continuously differentiable (C 1) state feedback for a class of uncertain nonlinear systems whose linearization around the origin may contain uncontrollable modes. Based on utilizing the homogeneous domination approach, we not only propose conditions of constructing a global continuously differentiable (C 1) controller, but also provide explicit design schemes for such systems. Finally, a numerical example demonstrates the effectiveness of the result. © 2015 Keylan Alimhan et al. Source

This paper considers the global practical tracking problem by state feedback for a class of high-order non-linear systems with more general uncertainties, to which the existing control methods are inapplicable. We successfully propose a new tracking control design scheme for the system studied by introducing sign function and necessarily modifying the method of adding a power integrator. It is shown that the designed controller guarantees that all states of the resulting closed-loop system are globally bounded and the tracking error remains prescribed arbitrarily small after a finite time. © 2016 SERSC.

In this paper the methods of structural and dimensional synthesis of a parallel manipulator with two end-effectors are presented. Parallel manipulator with two end-effectors is formed from two serial manipulator by connecting of their links by binary links with two revolute kinematic pairs. Geometrical parameters of the binary link have been determined at three, four and five finitely separated position of the end-effectors. © Springer International Publishing Switzerland 2016. Source

The problems of developing new generation knowledge acquisition systems are faced. A crucial role of measurement in acquiring knowledge for intelligent systems is shown. A comparative analysis of classical measurements and expert estimates is made. Some non-classical measurement concepts based on granular ontologies and measurement information granulation are presented. The classification of non-traditional measurements is given. The Russian scientific tradition of considering measurement as a cognitive process is discussed. The concept of Cognitive Measurement based on Cognitive Sensors is introduced. Here Cognitive Measurement is viewed as a two-leveled granulation process where the lower level is responsible for obtaining fine-grained data by artificial sensor system, and the higher level transforms it into coarse-grained information related to a pragmatic scale of normative linguistic values such as "norm", "nearly norm", "out of norm", "far from norm" etc. Two types of Cognitive Sensors with appropriate pragmatics are introduced. A bilattice-based interpretation of multi-sensor data fusion is proposed. © 2015 IEEE. Source
