MATLAB: Creating and naming Simulink Buses

busnamingsimulinkstruct

Hi!

I want to use buses in Simulink, and give them proper names. Some are created from a struct in an m script using:

 busInfo = Simulink.Bus.createObject(myStruct);

First: in emldemo_bus_struct, where are MainBus and SubBus created and named? They are used in the blocks by setting the type to Bus: MainBus

Second: How can i give any other name than slBus1 when creating the bus in Matlab?

thanks, Håvard

MainBus and SubBus for this demo are loaded from a MAT-file calld businfo.mat - they are loaded from the PreLoadFcn model callback function (right-click on model and select Model Properties>Callbacks>PreLoadFcn). The name of the bus is determined by the name of the Simulink.Bus object in the workspace. You can name it to whatever other name you prefer.

MATLAB: How to populate the signal names to match the bus object signal names in the Bus Creator block in Simulink 6.6 (R2007a)

The ability to assign signal names automatically from the specified Bus Object is not available in Simulink 6.6 (R2007a).

It is possible to create a script that automatically assigns the names specified in the Bus Object Elements to the signals connected to the bus object. For an example, download the attached files MainBus.mat, BusToBeNamed.mdl and DefineInputs.m. The Simulink model contains a Bus Creator block assiciated with a Bus Object. The following example MATLAB code can be used to assign the appropriate names to the signals connected to the bus.

load MainBus
open_system('BusToBeNamed');
S = Simulink.Bus.objectToCell({'MainBus'});
blk = 'BusToBeNamed/Bus Creator';  
ph = get_param(blk,'PortHandles');
lh = get_param(ph.Inport,'Line');
N = length(S{1}{4});
for i = 1:N
      set(lh{i},'Name',S{1}{4}{i}{1});
end

MATLAB: Generate a variable bus from within a mask in Simulink

You need to use evalin or assign in functions to create required variable in base worksspace from Mask workspace.

For example, in Mask workspace use something like this.

% An example structure to be converted to bus
myStruct.a = 10;
myStruct.b = 20;
% Create bus object in base worksapce with default name and collect its info
busInfo = Simulink.Bus.createObject(myStruct);
% Copy the created object with name you want and delete default object
evalin('base', ['myBus=' busInfo.busName ';clear ' busInfo.busName]);
