Constant Gain

Overview

Overview

Description

The Gain block multiplies the input by a constant gain value., the output is calculated at the update rate, which is determined by the Evaluate Block.

Example

This example shows how to construct a PID Filter from scratch, the Constant Gain block is used for Kp (Proportional Gain) and Kd (Derivative Gain).


The following parameters are used to configure this block:

 
K

Gain. Output = Input * K

Evaluate Block This block allows you to specify whether the block executes Every Sample, Every Other Sample (Odd or Even), or Every Fourth Sample (and specify the First, Second, Third, or Fourth) or background. This provides greater flexibility in controlling the execution of a model and to preserve performance for other areas of motion control.
User Defined Block Priority When selected, allows you to enter a Priority Code to modify Execution Ordering of this block. For more information, see Block Execution Order and User Defined Block Priority.
Priority For an explanation of how the Priority field is used by the MechaWare Model Downloader, see Block Execution Order and User Defined Block Priority.
User Data 0 Application-specific data. See User Data Storage.
User Data 1 Application-specific data. See User Data Storage.

Simulink Interface

gain_sim1

The Output of a Gain block is the Input multiplied by the gain (K).

The block has two user data fields (User Data 0, User Data 1) to store application-specific data for convenient storage and retrieval. See User Data Storage for details.

The block's update schedule is determined by the Evaluate Block. The following Parameter Dialog Box can be opened by double-clicking on the block in a Simulink Model:
