I am designing a controller. I have certain logical conditions on which one of the two controllers i.e. Main controller and sub controller is to be selected . I am using an "if block" with two "if action" sub blocks for selection. The output of both the controllers is a 3x1 vector. Now "if block" will select the controller based on certain conditions. But how to select one of two outputs from the controllers is my problem!! Kindly see the attached Simulink model for more clear idea of my problem. I have already tried merge and mux blocks but both of these cannot select one of the outputs.

Nothing is attached. Edit your original post and this time, use the paperclip icon to attach a file, or the frame icon to insert a picture.

Merge Block will work fine here as 1 output at a time will be enabled by IfElse Block.
Goto: https://in.mathworks.com/help/simulink/slref/merge.html for more details.

No, Switch Block is not at all encouraged for combining two inputs from If action Subsystems.Merge block is what MathWorks also suggest.
Please enable signal Dimension and Port data type so that I will be able to see what is coming from If Action Subsystem.
  1. Goto: Display>>signal Dimension
  2. Goto: Display>>Port data type
and if possible attach the model here I will look into it. or reach me on mail astiksachan8@gmail.com

Thanks Alot Astik. The Merge block is working and there was a problem in my model in if else block. Thanks for your support.
