AN APPLICATION OF THE DIRECT IDENTIFICATION OF PHYSICAL PARAMETERS TO DISTRIBUTED SYSTEMS

This paper gives an application of the technique of direct identification of physical parameters to distributed systems. A number of simulated results show that the matrices of physical parameters of evenly distributed systems can be identified using equivalent lumped parameter models'and the behaviour of the distributed systems can be approximated quite well by the behaviour of the estimated discrete systems. And some of the conclusions obtained through! the discrete models can still be obtained as when the distributed models are employed. Both the computer simulation and the experimental procedure all prove the fact that equally spaced measurements must be taken as the time responses arc measured from evenly distributed systems.
