Write to a block state

Library:
Simulink / Signal Routing

Description

TheState Writerblock sets the state of a supported state owner block. When creating a library block with aState Writerblock also include the state owner block.

Add aState Writerblock to your model from the Simulink^®Library Browser.

State Writerblocks can write state to these state owner blocks:

Discrete State-Space
Discrete-Time Integrator
Delay
Unit Delay
Discrete Transfer Fcn
Discrete Filter
Discrete FIR Filter
Integrator
Second-Order Integrator
Conditional subsystem blocks such asEnabled Subsystem,Triggered Subsystem, andFunction-Call Subsystem.
S-Functionwith multiple discrete states.
To configure an S-Function block as a state owner block, exactly one data type work vector must be declared as discrete state vector using ssSetDWorkUsedAsDState and named using ssSetDWorkName or ssSetDWorkRTWIdentifier in mdlInitializeSizes.

Input

`In`— State value
scalar | vector

State value written to a state owner block.

When writing to a state owner block with an input scalar, the scalar value is expanded to match the dimension of the state. All elements of the state are set to the same value.

Parameters

Model Examples

Working with the Initialize Function, Reset Function, and Terminate Function Blocks

Use the Initialize Function, Reset Function, and Terminate Function blocks to read and write states in a Simulink model.

Open Model

Reading and Writing States with the Initialize Function and Terminate Function Blocks

In this example, the Initialize Function block uses the State Writer block to set the initial condition of a Discrete Integrator block to 10.
