摘要

A new method forcompensating the space discretization error introduced when the fixed is considered for the dynamic models of temperature distributions is presented. It is proved that the method generally used in literatrue is a particular solution of the proposed one. Moreover, it results in a continuous-time model, for which the integrating method becomes a free choice and a state-space representation is possible. The umerical model was experimentally validated, the comparison, both in the time and in the frequency domains, between simulation and measrued results showing good agreement. The presented dynamic model increases the calculation speed and it can be analysed with the tools developed in control theory.
