recordChuaData
Parameter for Chuas diode
Extends from Modelica.Icons.Record (Icon for records).
Information
The Chua diode can be implemented from 2 NICs, either ideal or as opAmp-circuit. Therefore this parameter record contains 2 NIC parameter records and calculates analytic parameters. Looking at the formula, it is possible to design the NICs from desired analytic parameters:
Ve = NIC1.VLim = Vs*NIC1.Rg/(NIC1.Rg + NIC1.R)
Ga = -1/NIC1.Rg - 1/NIC2.Rg
Gb = 1/NIC1.R - 1/NIC2.Rg
Gc = 1/NIC1.R + 1/NIC2.R
Vp = NIC2.VLim = Vs*NIC2.Rg/(NIC2.Rg + NIC2.R)
Thease are 5 equations for 5 parameters: NIC1.{R, Rg}, NIC2.{R, Rg} and Vs.
