Divide

Divide two signals: y = a / b. Keep the denominator away from zero.

Description

Divides the first input by the second.

Example

Arithmetic Sum, difference, product, quotient, minimum, and maximum of a ramp and a constant.

a = tb = 2a + ba − ba · ba / bmin(a, b)max(a, b)
In Gradara, select a Divide block and press F1, then choose Open example. It opens as a new model in My models, ready to run.

Ports

Inputs 2

  • asignal

    Numerator.

  • bsignal

    Denominator.

Outputs 1

  • ysignal

    Output signal, a / b.

Equations

Modelica
y = a / b

Implementation

The block’s Modelica model
y = a / b;

Assumptions and limitations

  • The denominator is not guarded. If b reaches 0 during a run, the division fails and the simulation stops with an error.

Tips

  • If b can pass through zero, keep it away from zero first, for example with Max against a small constant or with Saturation.
