Abstract

Object oriented approach for large circuits with substructures in the computer algebra program Maple V A. Kugi,* K. Schlacher,* M. Kaltenbacher* ^Department of Automatic Control, Johannes Kepler University, A-4040 Linz Auhof, Austria * Department of Electrical Measurement, Johannes Kepler University, A-4040 Linz Auhof, Austria This paper is concerned with the symbolic derivation and solution of the minimal set of network equations in MapleV. By means of the table en- vironment of MapleV it is possible to realize the essential features of an object oriented design. All considered linear electric terminals are arranged in a class hierarchy using the principle of multiple inheritance. The net- work algorithm for setting up the equations is based on the recursive graph searching method depth first. The algorithm is extended by a special sub- structure technique, in order to be able to calculate complex networks with a higher number of network elements. Finally, the feasibility of the p
