Analysis of switched systems using the bond graph methods
(Elsevier Science Ltd, 1999) Poyraz M.; Demir Y.; Gülten A.; Köksal M.
In recent years, the analysis of switching systems has gained importance. In this paper, the formulation of state and output equations and solutions of switched-systems are presented by using the bond graph model with a new simple and more general switch definition. The theory is illustrated by a few examples and the output of the computer programme called BOMAS is presented.
Remark on the lumped parameter modeling of transmission lines
(2000) Mamiş M.S.; Köksal M.
Transmission lines are distributed parameter systems. Instead of distributed parameter models, lumped parameter models are also used for steady-state and transient analysis of transmission lines. Lumped parameter modeling for transmission lines is obviously an approximation. This paper aims to investigate the theoretical error in the lumped parameter modeling of transmission lines for steady-state and transient analysis. To determine the error, steady-state and transient responses of the transmission line are calculated by using both distributed and lumped parameter modeling. The effect of number of sections used for lumped parameter modeling is investigated. Obtained results can be used for the determination of the number of sections. Copyright © 2000 Taylor & Francis.
