Robust System Modelling Using Bi-lateral Delay Lines
2005 (English)In: Simsafe 05,2005, 2005Conference paper (Refereed)
A very suitable method for modelling and simulation of large complex dynamic systems is represented by dis-tributed modelling using transmission line elements (or bi-lateral delay lines). This method evolves naturally for calculation of pressures when hydraulic pipelines are modelled with distributed parameters. It is also applicable to other physical systems, such as mechani-cal, electrical, gas etc. One interesting application for distributed solvers using bi-lateral delay lines is in real time simulation. Modelling for real-time applications puts special requirements on robustness in the numeri-cal methods used. In real-time applications there is no room for decreasing time step in numerically critical stages. Furthermore, if a system is relaying on a real-time simulation for its functionality, failure in the nu-merical properties is unacceptable.
