This only works if, for all block expressions, the order of the numerator is equal to or greater that the order of the denominator. I tried this using Matlab R2015b and since I had a '2s' component the 'blockbuild' function gives an error message.
Sir I got an error. it is not working if any block of tf have order of numerator is greater than denominator. Order of denominator should be greater or equal to numerator it is saying that.please help me sir .
For a realisable system, the order of the numerator should be less than order of denominator. In such case, you can break the numerator polynomial in to parts and cascade the system.
The parameters; a, b, c, and d specified in the connect() function are set by the 'blkbuild' command. From the MATLAB docs for the output of 'blkbuild': "[a, b, c, d] is the resulting state space structure. The matrices are built up by progressive APPENDs of the state space representations of each block."

Thanks man really helped. Saved my enormous time
Glad it helped
Thanks for world class lecture professor 😚

It's really helpful sir, looking forward for more content.
nice tutorial,keep it up!!!well explained
Sir, i think you should upload more videos. It's really helpful.
Nitin Kaushik sure .... In due course it will be done
Great brother
Thanks

I am confused what a,b,c represent in the connect function
The parameters; a, b, c, and d specified in the connect() function are set by the 'blkbuild' command.

@@genericaccount7422 thnx
For feedback system I got (s² +3s +2) in numerator
blkbuild undefined why?????
Blkbuild will take the q matrix and construct the blocks according to the entries in q matrix
I want the pdf of this lce
maybe im making a mistake but from the cascade system im getting a num=[1 2 1]. Anyone else?
Yes, i have just verified it via MATLAB. A little mistake in the first example of the video :(
Thanks for taking the effort to reconfirm
