Abstract:
A simulation apparatus simulating dynamic performance of a target apparatus, which includes a plurality of units performing non-linear operation and energy is transmitted therebetween, said simulation apparatus comprising:functional modeling means for modeling each unit by functional models, including at least a first parameter that determines dynamic performance of each respective unit, in which exchange of energy according to the dynamic performance of each unit is defined by product of a potential variable that expresses a potential of the energy and a flow variable that expresses a flow of the energy and coupling each of the functional models via a pair comprising the potential variable and the flow variable;data storage means for storing, in advance, non-linear characteristic data of each unit as functions or tables;data modeling means for, when simulation of the dynamic performance of the target apparatus is performed, generating, by using pre-stored mechanism models depending on an actual mechanism of each unit, at least a second parameter of each unit on the basis of the characteristic data for the respective unit read from said data storage means at every predetermined sampling period of time; andsimulation control means for simulating the dynamic performance of the target apparatus by setting the generated second parameter as the first parameter of said coupled functional models at each predetermined sampling period of time and outputting a simulation result of the dynamic performance of the target apparatus.
