文摘
- •
An analytical dynamic model of the longitudinal temperature of an electric wire involving a special implicit transfer function with an exponential is presented.
- •
A meshed model (spatial discretization) is proposed to obtain an accurate integer order approximation of this kind of transfer function.
- •
The spatial discretization is optimized through a criterion based on the H2-norm of the error transfer function between the analytical model and its meshed approximation.
- •
Accuracy of the meshed model is evaluated with measured data from dedicated benchmark and compared to other models obtained from classical frequency identifications.
