simulink :Control System: MIMO Observer

I am trying to implement in Simulink observer (MIMO).

I got stuck with two errors.

The errors are mentioned in the pdf.

Is there any error in connection of the blocks?

Please sujjest some way.

What is the size of K?

Answer 1

[Azzi Abdelmalek]

I don't know what kind of observer you are using, can you explain what are the sizes of the observer model (A1,B1,C1,D1), and the size of your feedback gain K

[abhijit kulkarni]

Dear Sir

A1=6x6, B1=6x2,C1=6x2,D=[0];
Observer gain=2x6

[Azzi Abdelmalek]

From your chart the observer output is 6x1 , it will be multiplied by a gain vector 2x6, this is not doable, the same thing for the observer inputs, it should be 2 inputs while the chart shows 4

[abhijit kulkarni]

Rightly said Sir.

I want to know in what way should it be corrected; should feedback gain matrix be 1X6 ? If F=2x6 then what modification is required? I am trying to rectify my mistake in parallel .
