How to represent this state space form in Simulink model?

With the orginal mathematical equation I got this

and build the Matrix

How should I build my Simulink Model accordingly for a 4th-order system it should have 4 integrator, but according to x4dot, there are x2steady-state missing, here is what I have now for my model

How should I modify the red area I mard to get the desired output response

Drop 4 integrators (1/s) into your model, do not connect them to anything yet.

Draw signal wires leading in and out of each integrator.

Enter names for each signal wire like so

Integrator Input Label Output Label

1st x1_dot x1

2nd x2_dot x2

3rd x3_dot x3

4th x4_dot x4

Use your four equations dx1/dt, ... dx4/dt

to quide what signals and operations should be wired together to form the signal x1_dot, ... x4_dot
