Signal Generator Work Around

Signal Generator Work Around

Signal Generator Work Around


I am trying to use simulink to test multiple actuators depending on the type of control, longitudinal, collective, lateral etc.. I have my simulink model set up where I can make the actuator type selection via GUI to feed my simulink model the parameters for a longitudinal, collective, lateral control etc.

I am at the point where I want to use the signal generator to test various performance requirements specific to each actuator. Is there a way I can select which index signal I want run without simulink generating all the signals in the signal generator? I have tried doing this manually using a multichannel switch, but the run time is slow because simulink calculates the signals even if they are unused.. So what I am looking for is the most efficient way that can be interfaced with GUI.

RE: Signal Generator Work Around

It doesnt seem like there is an enabler. Thats why I had to use a multiswitch along with all of the output ports from my signal generator to select which signal I wanted to pass forward.

Generating my signal would be possible, however It wouldnt be practical if I needed to modify any of the signals quickly.

RE: Signal Generator Work Around

How do you do that?

RE: Signal Generator Work Around

Solution found. You can change groups from the command window.

e.g. if I have a .mdl named mike, and lets say my signal builder is in a subsystem called hello this would be how to access it.
You can also double click on signal builder block and get the 'mike/hello' reference from the bar at the top of the signal builder GUI.

signalbuilder('mike/hello','activegroup',(enter group index #))
