| Apr 14, 2013 at 14:17 | comment | added | user50222 | I went like: $$X_2(s) = (U(s)-X_1(s)) \cdot \frac {b}{s+p} $$ $$X_1(s) = X_2(s) \cdot \frac {k}{s+a}$$ That could mean: $$sX_2(s) + pX_2(s) = bU(s) - bX_1(s) \to \dot x_2(t) = bu(t) - bx_1(t) - px_2(t)$$ $$sX_1(s) + aX_1(s) = kX_2(s) \to \dot x_1(t) = -ax_1(t) + kx_2(t)$$ and output sould be: $$y(t) = x_1(t)$$ that would lead to matrices I wrote. But I don't know, if I can do that this way, or if that is what was the task, cause we were told not to transfer to time domain, but I can't imagine how to do it without transfer I did. | |

You say I have no idea, how to do this and yet you present an answer. Can you detail how you got your answer, and what you don't understand about it?

| Apr 13, 2013 at 19:00 | comment | added | user50222 | No, that would not help. I would prefer if enybody could tell, how to solve it. Cause I don't understand it. | |
| Apr 13, 2013 at 16:55 | comment | added | Peter K.♦ | Would it help if you knew that the transfer function of a system described by $[A,B,C,D]$ is $C(s{\bf I} - A)^{-1}B + D$ ? | |
| Apr 13, 2013 at 14:43 | comment | added | user50222 | I thought it is globaly used. Exactly what matrices at en.wikipedia.org/wiki/State_space_representation means. | |
| Apr 13, 2013 at 13:34 | comment | added | Jason R | You should define what the matrices $A, B, C, D$ refer to in your state-space model. Then it should be pretty easy to tell if you're right. | |
