✦ Synopsis
Analysis and simulation of non-linear inverse systems are sometimes necessary in the design of control systems particularly when trying to determine an input control required to achieve some prede"ned output speci"cations. But unlike physical systems which are proper, the inverse systems are very often improper leading to numerical problems in simulation as their models sometimes have a high index when written in the form of di!erential-algebraic equations (DAE). This paper provides an alternative approach whereby performance speci"cations and the physical system are combined within a single bond graph leading to a greatly simpli"ed simulation problem.
