Opis:
Affine discrete-time control periodic systems are considered. The problem of global asymptotic stabilization of the zero equilibrium of the closed-loop system by state feedback is studied. It is assumed that the free dynamic system has the Lyapunov stable zero equilibrium. The method for constructing a damping control is extended from time-invariant systems to time varying periodic affine discrete-time systems. By using this approach, sufficient conditions for uniform global asymptotic stabilization for those systems are obtained. Examples of using the obtained results are presented.

Opis:
This paper is concerned with adaptive stabilization of two coupled viscous Burgers' equations by nonlinear boundary controllers. Under the existence of bounded deterministic disturbances, the adaptive controllers are constructed by the concept of high-gain nonlinear output feedback and the estimation mechanism of the unknown parameters. In the controlled system the global stability and the convergence of the system states to zero will be guaranteed. It is shown that the theory can be generalized to the systems with higher-order nonlinearity.

Macroeconomic Stabilization Pentagon

Central and Eastern Europe
Opis:
The model of the macroeconomic stabilisation pentagon allows for a quick insight into the most important macroeconomic indicators of an economy in question. On the basis of this concept -comparing pentagrams for particular years - changes of the economic condition of countries can be examined. Moreover, the analysis of each of the adopted criteria allows for the evaluation of achievement of particular goals by a country in terms of its economic policy. The aim of this article is to describe the condition of Central and Eastern Europe countries in the years 2007-2010. The economies analysed were compared at two levels. The first level concerned the macroeconomic situation of all economies in particular years just before and during the global economic crisis. At the second level, the changes in the analysed indicators in particular economies of Central and Eastern Europe were compared. The results of the analysis shall contribute to the formulation of conclusions concerning the influence of the financial crisis upon the macroe-conomic situation of the CEE countries.

Opis:
Ultimate state boundedness for underactuated spacecraft subject to large non-matched disturbances is attained. First, non-smooth time-invariant state feedback control laws that make the origin asymptotically stable are obtained. Then, the controller is extended to make the closed-loop system globally uniformly ultimately bounded under the following conditions: 1) the disturbances acting on the directly actuated states are known and 2) the disturbance acting on the unactuated state is bounded and its profile need not be known. Finally, numerical simulations are presented to verify the analytical results. A large step disturbance is considered, and it is shown that the proposed controller makes the closed-loop system globally uniformly ultimately bounded. The proposed method is rather general and can be extended to other systems.

Opis:
The article focuses on selected theoretical aspects of anti-crisis stabilization policy and policy exit strategies. The author looks at the approach to macroeconomic stabilization policy prior to the latest financial and economic crisis and discusses specific aspects of the anti-crisis policy. These include the problem of the liquidity trap in monetary policy, the effectiveness of discretionary fiscal packages, differences in the ways of maintaining international competitiveness by countries pursuing an independent monetary policy and those that are member states of the European monetary union. The author also takes a look at new European Commission initiatives for monitoring macroeconomic stability. He concludes that the latest global crisis has led to significant adjustments in methods for pursuing a stabilization policy, although the basic theoretical assumptions have remained unchanged.

Opis:
This paper is a contribution to the following question : consider the classical wave equation damped by a nonlinear feedback control which is only assumed to decrease the energy. Then, do solutions to the perturbed system still exist for all time? Does strong stability occur in the sense that the energy tends to zero as time tends to infinity? We prove here that the answer to both questions is positive in the specific case of the one-dimensional wave equation damped by boundary controls which are functions of the observed velocity. The main point is that no monotonicity assumption is made on the damping term.
