Slider Gain

R2026b

Vary scalar gain using slider

• 

Slider Gain block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink / Math Operations

Description

The Slider Gain block performs a scalar gain that you can modify during simulation. Modify the gain using the slider parameter.

Examples

Simulate Motion in Six Degrees of Freedom (6DOF)

Model six degrees of freedom (6DOF) motion in Simulink® using the 6DOF (Euler Angles) (Aerospace Blockset) or 6DOF (Quaternion) (Aerospace Blockset) blocks. The model replicates the motions experienced by an object or vehicle, including three axes of rotation (pitch, roll, and yaw) and three axes of translation.

Ports

Input

Port_1 — Input signal

scalar | vector | matrix

The Slider Gain block accepts real or complex-valued scalar, vector, or matrix input. The block supports fixed-point data types.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point

Output

Port_1 — Input multiplied by gain

scalar | vector | matrix

The Slider Gain block outputs the input multiplied by a constant gain value. When the input to the block is real and gain is complex, the output is complex.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point

Parameters

Slider gain — Gain value

0 (default) | real value

Chose the gain value applied to the input.

Programmatic Use

Block Parameter: gain

Type: character vector

Values: real scalar

Default: '1'

Low — Lower limit of slider range

0 (default) | real value

Specify the lower limit of the slider range.

Programmatic Use

Block Parameter: low

Type: character vector

Values: real scalar

Default: '0'

High — Upper limit of slider range

2 (default) | real value

Specify the upper limit of the slider range.

Programmatic Use

Block Parameter: high

Type: character vector

Values: real scalar

Default: '2'

Block Characteristics

Data Types	Boolean | double | fixed point | integer | single
