An engineering system may consist of several different types of components,belonging to such physical"domains"as mechanical,electrical,fluid,and *** is termed a multi-domain(or multi-physics)*** present paper concerns the use of linear graphs(LGs)to generate a minimal model for a multi-physics system.A state-space model has to be a minimal ***,the number of state variables in the model should be the minimum number that can completely represent the dynamic state of the *** choice is not ***,state variables are assigned to all the energy-storage elements of the ***,some of the energy storage elements may not be independent,and then some of the chosen state variables will be *** approach is presented in the paper,with illustrative examples in the mixed fluid-mechanical domains,to illustrate a way to recognize dependent energy storage elements and thereby obtain a minimal state-space *** analysis in the frequency domain is known to be more convenient than in the time domain,mainly because the relevant operations are algebraic rather than *** achieving this objective,the state space model has to be converted into a transfer *** direct way is to first convert the state-space model into the input-output differential equation,and then substitute the time derivative by the Laplace *** approach is shown in the *** same result can be obtained through the transfer function linear graph(TF LG)of the *** a multi-physics system,first the physical domains have to be converted into an equivalent single domain(preferably,the output domain of the system),when using the method of *** procedure is illustrated as well,in the present paper.
