Hi everyone,
am working on state fedback using state observer for controlling a DC motor, i have a problem in the analog signals output. many signal instead of one....
same goes for speed and phase shift. any idea why
this is the overall simulink model

after simulation, below is the output analog current result, why am getting all these signal unstead of one ?

I expect somewhere in your model you have a matrix or vector oriented in the wrong way. Or have the wrong option selected in a vector gain.
To help troubleshoot, it would be helpful to look at the signal dimensions.
In the simulink go to Display > Signals & Ports > Signal Dimensions and you should be able to get a better idea of where it is going wrong.
