✦ Synopsis

A designer can use a mathematical model ot a physical system to study its dynamic performance. The goal of the Design Analysis for Reliability Tool (DART) project at the IBM Thomas J Watson Research Center was to automate some of the steps of building mathematical models. The bond-graph method was used to represent a physical system as a lumped parameter model. The DART program accepts a bond graph entered through a graphic editor. State equations are automatically derived from the bond graph. Specific constitutive laws k~r the general relationships represented by the bond-graph nodes are entered through a full-screen editor. The equations are solved using the Dynamic Simulation Language ( DSL). mathematk:al modelling,

In this paper, the pole assignment problem is considered for linear systems modelled by bond graphs. A procedure for the .fbrmal determination of the controllability matrix is proposed. This matrix is used to transform the state and control matrices into a controllability,form. It allows us to j&mal
