Description

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

$$\begin{eqnarray} y&=&x1\\ \dot{x_{1}}&=&B\left(u-x_{1}+x_{2}\right)\\ \dot{x_{2}}&=&Cx_{1} \end{eqnarray}$$

where B and C are vector of parameters, u a vector of inputs and y the vector of outputs, $x_{1}$ $x_{2}$ the vectors of the continuous state variables.

Dialog box

• Initial condition 1
  The initial condition of the time state variable x1.
  Type 'vec' of size -1.

• Initial condition 2
  The initial condition of the time state variable x2.
  Type 'vec' of size -1.

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

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