MATLAB: Are SimPowerSystem blocksets supported on xPC Target 4.0 (R2009a)

simpowersystemsSimscape Electricalxpc

I have designed a SimPowerSystems model and would like to load it on xPC target. I would like to know if it is possible to generate code for SimPowerSystems model and port it to xPC Target machine.

Best Answer

Yes, one can generate code for a SimPowerSystems model and port it to an I/O board or xPC Target.

However one cannot generate Embedded code i.e. it cannot generate code for xPC Embedded Target and Real-Time Workshop Embedded Coder.

MATLAB: Is it possible to use Real-Time Workshop on a Simulink model containing blocks from the SimPowerSystems Blockset

You can use the Real-Time Workshop on models that contain Power System blocks, however, there are a couple of caveats:

1. You will not see in the generated code the individual powerlib elements and labels. You will only see the equivalent State-Space representation of the elements that Simulink uses in its dynamic simulation. For more on how this representation is created, see following documentation by entering the following command in MATLAB:

web([docroot '\toolbox\physmod\powersys\powersys_product_page.html'])

2. Real-Time Workshop currently does not support the variable step stiff solvers that are often the most optimal for use with the SimPowerSystems Blockset. Therefore, code generated with Real-Time Workshop will currently have to use one of our fixed-step Solvers.

For Release 12 and higher:

------------------------------------------

If you are using Release 12 or higher of MATLAB (version 6.0) and version 2.0 or higher of the SimPowerSystems Blockset, you can discretize the power system portion of your Simulink model. This allows you to run fixed-step solvers on your model and, in turn, generate code through Real-Time Workshop with a fixed-step solver.

This capability also has the effect of removing (ignoring) aspects of your simulation that cause stiffness in the ODEs. Sometimes this is appropriate and sometimes it isn't. If discretizing your model works for your applications, then this methods can be used to generate code through Real-Time Workshop.

For more information on this, see pg. 1-22 of the Power System's User's Guide or enter the following at the MATLAB command prompt:

MATLAB: Does the “power_battery” link from Battery block in SimPowerSystems documentation take me to the “power_breaker” model instead in SimPowerSystems 5.1 (R2009a)

This change has been incorporated into the documentation in Release 2010a (R2010a). For previous releases, read below for any additional information:

This is a bug in the documentation for SimPowerSystems 5.1 (R2009a). To open the correct model type

power_battery

in the MATLAB command window.
