Syntax

Simulink.fault.enable(modelElements,status)

Description

example

Simulink.fault.enable(modelElements,status) enables or disables the model elements, modelElements, for fault injection based on the value of status.

Examples

collapse all

Open a model with a block that supports fault modeling.

openExample('simscape_shared/SimpleMotorArmatureWindingFaultExample')

Add a fault to the Armature winding model subelement in the DC Motorblock called myFault.

Simulink.fault.addFault(...
"SimpleMotorArmatureWindingFault/DC Motor/Armature winding",...
Name="myFault")
ans = 

  Fault with properties:

            Name: 'myFault'
     Description: ''
    ModelElement: 'SimpleMotorArmatureWindingFault/DC Motor/Armature winding'
            Type: 'Simscape'
        IsActive: 0

Assign behavior to the fault and store the behavior in a fault model named myBehaviorModel on the path.

addBehavior(myFault,"myBehaviorModel");

Enable the fault.

Simulink.fault.enable(...
"SimpleMotorArmatureWindingFault/DC Motor/Armature winding",true)

Input Arguments

collapse all

Paths or handles of model elements, specified as a string array, cell array of character vectors, or a vector of handles. If you specify only one model element, enter it as a scalar.

Each entry in the array must be the path of a fault-capable model subelement.

Example: "myModel/DC Motor/Armature winding"

Example: ["myModel/DC Motor/Armature winding" "myModel/RC Servo/Servo"]

Example: ['myModel/DC Motor/Armature winding', 'myModel/RC Servo/Servo']

Data Types: string | char | double

Enabled status of model elements, specified as a numeric or logical 1 (true) or 0 (false). Enter 0 or false to disable fault injection on the model elements. Each model element must have at least one fault that has behavior.

Data Types: logical
