The Sense internal variables feature

Sense internal variables scope: control applications or signal processing

Sense internal variables This feature allows you to access some of a component's internal variables that are not provided at ports even though these variables can be interesting for control applications or for signal processing. Sensed variables are converted to signals and each of them is associated with a unique port. These signal ports can then be connected with standard Simcenter Amesim components such as:

1. Control related components:

Interface blocks, typically for sending sensed internal variables to a Simulink controller model that uses them for its control strategy.

Control components, for instance a PID controller, for designing the control loop within the Simcenter Amesim environment. These components can be found in the Signal, Control Library.

2. Signal processing components: typically for writing an ASCII file containing the values of a sensed variable. These components can also be found in the Signal,Control Library.

3. Components from the Simulation Library: for example to be able to stop a simulation based on the values of a sensed internal variable, typically if an undesired threshold is reached.

4. Components converting signals to physical quantities: all the actuators or "signal to physics" sources from the various physical libraries of Simcenter Amesim.

You can also use sensed internal variables to define optimization criteria. However, control applications and signal processing are the main scope of the Sense internal variables feature.

Note

Submodel Editor remains the standard tool for creating and sharing variant components to be reused and stored into libraries when additional ports are needed.
