Description

This block realizes the sub-system G of Chua's circuit :

$$\begin{eqnarray} y&=&x\\ \dot{x}&=&\alpha\left(u-x-\left(m_{1}x+\frac{1}{2}\lef... ...ert u+E\right\vert-\left\vert u-E\right\vert\right)\right)\right) \end{eqnarray}$$

where $m_{0}$, $m_{1}$ and $\alpha$ are vectors of parameter, u the vector of inputs, y the vector of outputs et x the vector of the continuous state variables. (E=1)

Dialog box

• Initial condition
  The inital condition of the output.
  Type 'vec' of size -1.

• A
  The linear alpha gain value.
  Type 'vec' of size -1.

• m0
  The m0 slope value of the nonlinear function.
  Type 'vec' of size -1.

• m1
  The m1 slope value of the nonlinear function.
  Type 'vec' of size -1.
