Exponential

The exponential function block in the control elements performs this operation with a real input, following the expression:

$$y_n = \bold{A} e^{\bold{B} u_n}$$

Where:

• $u_n$ and $y_n$ are the input and output of the exponential block, respectively;
• $\bold{A}$ and $\bold{B}$ are constants defined by the user.

The figure below shows the exponential block data editing form:

This nonlinear block is defined by the constants A and B, entered by the user.

Information

Such blocks are useful for representing nonlinearities, for example, modeling the saturation of DC machines present in some automatic voltage regulators.
