A Virtual Instrument for the Characterization of Nonlinear Components under Non-sinusoidal Condition
نویسندگان
چکیده
In the paper a new method for the measurement of R, L, C parameters under non-sinusoidal condition is proposed. The measurement procedure, starting from the consideration that for a non-linear SISO system the discrete transfer function H(z) functionally depends on the applied input, uses the estimated z parameters to obtain the best estimate of the equivalent circuit R, L, C parameters of first and second order systems. The method is implemented by a virtual instrument based on IEEE-1155 and IEEE-488 measurement systems. The realized instrument is vatidated with reference to many experimental results obtained in both on-line and off-line tests.

A previously introduced two phase model was used to assess its capability in predicting the behavior of reinforced soil walls under working stress conditions. The two phase model is a homogenization method based on the virtual work theorem. The reinforced soil medium is considered as the superposition of two continuous phases, the reinforcement and matrix phases that interact within the medium....
