Ramp - Generate constantly increasing or decreasing signal

Library

Sources

Description

The Ramp block generates a signal that starts at a specified time and value and changes by a specified rate. The block's Slope, Start time, and Initial output parameters determine the characteristics of the output signal. All must have the same dimensions after scalar expansion.

Data Type Support

The Ramp block outputs signals of type double. For more information, see Data Types Supported by Simulink in the Simulink documentation.

Parameters and Dialog Box

Slope

Specify the rate of change of the generated signal. The default is 1.

Start time

Specify the time at which the block begins generating the signal. The default is 0.

Initial output

Specify the initial value of the output signal. The default is 0.

Interpret vector parameters as 1-D

If you select this option and the other parameters are one-row or one-column matrices, after scalar expansion, the block outputs a 1-D signal (vector). Otherwise, the output dimensionality is the same as that of the other parameters. See Determining the Output Dimensions of Source Blocks in the Simulink documentation.

Examples

The following Simulink demos show how to use the Ramp block:
