- Abstract
- Co-simulation is widely used in industry for the simulation of multi-domain linear-time-invariant systems. However, as a result of the not continuous communication between our coupling variables, simulation results end up being unstable and inaccurate. Among the different strategies that have been developed in the recent years to control co-simulation drawbacks, the aim of this thesis is to understand the application of a sophisticated control theory technique, the H infinity synthesis method to an explicit-parallel co-simulation scheme in the frequency domain.

- Co-simulation is the simulation of dynamical systems described by differential equations, in particular, with linear time invariant systems. This systems can be so complex in general that it turns out advantageous to consider them in a decoupled way, so that the subsystems are solved separately, e.g.: co-simulation of the two masses of a dual mass spring damper system, or the co-simulation og MBD vehicle model and an EPAS system model. This separation introduces an error, the coupling error, that relies on the update of the shared information between the subsystems when they are being solved. The purpose of my thesis is to understand a sophisticated control theory approach, the H infinity synthesis method in order to minimize the coupling... (More)
