-The robustness of absolute stability of Lurie systems with multiple non-linearities, with respect to model variations, is considered. Two approaches for robustness analysis are developed. One is based on the Popov frequency domain criterion and the other on the algebraic criterion for the absolute stability. It is shown that there exist finite(More)
A recursive algorithm is developed for solving the algebraic equations comprising the solution of the optimal static output feedback control problem of weakly coupled systems. The proposed algorithm is very efficient from the numerical point of view, since only low-order systems are involved in algebraic calculations and the required solution can be easily(More)
ALINET is a network model designed for the analysis of energy use in the food processing and distribution sector and for the evaluation of the potential effectiveness of energy conserving technologies the basic structure of the model is that of a material flow network where nodes represent the specific state of the material at that stage and links represent(More)
ALINET, a network modeling system, is used as a tool for analyzing energy use in wheat production and processing in a Yugoslav enterprise. The basic structure of the model is that of a material flow network where nodes represent the specific state of the material at that stage and links represent the processes that the material is undergoing. The descriptor(More)
