Opis:
Algorithms of calculation of a state of an electric circuit with passive components are described. Algorithms are intended for usage in system of simulation of the mixed electronic devices. Each component of a circuit is presented by program model of high complexity. In this article the resistor model is described. Electric voltages in circuit nodes are calculated by method of summation of volt-ampere characteristics. Component models control iterations at calculation of circuit nodes voltage. Results of calculation of voltage in R-2R ladder of the digital-to-analog converter are presented.

Opis:
Certain approach to the modelling dynamic states in technical systems is presented in this paper. This approach lies in a replacing classic differential model with a model based on fuzzy relational cognitive map. Described method is illustrated by practical example of simple electrical RLC circuit. The method of the normalized reference data preparation was described. The process of building a cognitive map with concepts crucial from the modelling purposes point of view was presented also results of such a map teaching process were shown. In the end a partial comparison of simulation results of work of models: classic - based on the set of differential equations and proposed - based on fuzzy relational cognitive map was performed.

Opis:
The specific duality and asymptotic stability of the positive linear electrical circuits are addressed. The specific duality of positive linear electrical circuits composed of resistances, inductances, capacitances and source voltages is established. 1) The linear electrical circuits are positive if and only if the common branches between meshes with resistances and inductances and meshes with resistances and capacitances contain only source voltages; 2) In linear electrical circuits the interchanges of the inductances by the capacitances and the capacitances by inductances do not change the asymptotic stability of the electrical circuits. The asymptotic stability of the positive and nonpositive electrical circuits is analyzed.

Opis:
The analysis of the positivity and stability of linear electrical circuits by the use of state-feedbacks is addressed. Generalized Frobenius matrices are proposed and their properties are investigated. It is shown that if the state matrix of an electrical circuit has generalized Frobenius form then the closed-loop system matrix is not positive and asymptotically stable. Different cases of modification of the positivity and stability of linear electrical circuits by state-feedbacks are discussed and necessary conditions for the existence of solutions to the problem are established.
