  • PS Divide block

Description

The PS Divide block divides one physical signal input by another and outputs the quotient:

O=I1./I2

where

I1Physical signal at the first input port (marked with the x sign)
I2Physical signal at the second input port (marked with the ÷ sign)
OPhysical signal at the output port

The signal unit at the output port is determined by unit propagation rules. For more information, see Physical Signal Unit Propagation.

Ports

Input

expand all

First input physical signal, representing the numerator. In the block icon, this port is marked with the x sign.

The port name is not visible in the block icon, but you can see this name in the underlying source file (accessible by clicking the Source code link in the block dialog box).

Second input physical signal, representing the denominator. In the block icon, this port is marked with the ÷ sign.

The port name is not visible in the block icon, but you can see this name in the underlying source file (accessible by clicking the Source code link in the block dialog box).

Output

Output physical signal.

The port name is not visible in the block icon, but you can see this name in the underlying source file (accessible by clicking the Source code link in the block dialog box).

Model Examples

Nonlinear Inductor

Nonlinear Inductor

An implementation of a nonlinear inductor where the inductance depends on the current. For best numerical efficiency, the underlying behavior is defined in terms of a current-dependent flux. In order to differentiate the flux to get voltage, a magnetizing lag is included. Simulation results are relatively insensitive to this lag provided that it is at least an order of magnitude faster than the fastest frequency of interest. Parameters for the source and lag are defined in the MATLAB® workspace so that the expected voltage can be calculated analytically.

Solenoid

Solenoid

A solenoid with a spring return. The solenoid is modeled as an inductance whose value L depends on the plunger position x. The back emf for a time-varying inductance is given by:
