Suboptimálne riadenie systému s oneskorením na vstupe implicitným modelom The stabilization by feedback control of systems with input delays may be considered in various frameworks. In this paper the problem of implicit model following for input delay systems via optimal control is approached. The optimal control is implemented by piecewise constant signals that make it suboptimal. The simulati...

This study analyses some political factors determining budget deficit in Pakistan. It examines the short and long-run relationship between the Budget deficit, democracy and cabinet size for Pakistan’s economy. The bounds testing approach to co-integration and (ECM) error-correction models, developed within an autoregressive distributed lag (ARDL) framework is applied to annual data for the peri...

2010 Acknowledgement The study embraces the last two decades I worked for the Institute of Food Research, UK. For the opportunity to become a research scientist, I am indebted to Dr Terry Roberts, the former head of the Microbiology Department there, who decided that further advances in food microbiology was impossible without a dedicated mathematician.

The effect of the global financial crisis on the international trade patterns of developed countries has been one of the main focuses of recent studies. However, the dependence level of world trade on emerging markets increases every day. Therefore, it is important to study the level of the negative effect of the crisis on emerging economies and the level of their recovery potential. This paper...

The application of the Sliding Mode Thermal Control to dryer station furnace facility in agriculture productions is proposed. An adaptive controller is designed based on results obtained in the sphere of discontinuous system design. The derived Sliding Mode (SM) control algorithm written in Lab View environment should improve the control performance of the important characteristic of systems su...

This paper deals with the solution bounds for time-delay systems via delay-dependent Lyapunov– Krasovskiimethods. Solution bounds arewidely used for systemswith input saturation caused by actuator saturation or by the quantizers with saturation.We show that an additional bound for solutions is needed for the first time-interval, where t < τ(t), both in the continuous and in the discrete time. T...

A fast identification algorithm is proposed for systems with delayed inputs. It is based on a non-asymptotic distributional estimation technique initiated in the framework of systems without delay. Such technique leads to simple realization schemes, involving integrators, multipliers and piecewise polynomial or exponential time functions. Thus, it allows for a real time implementation. In order...

A new approach to robust sampled-data control is introduced. The system is modelled as a continuous-time one, where the control input has a piecewise-continuous delay. Sufficient linear matrix inequalities (LMIs) conditions for sampled-data state-feedback stabilization of such systems are derived via descriptor approach to time-delay systems. The only restriction on the sampling is that the dis...
