### How to find the transfer function from...

Hi all,

There is a state space system as follows:

X_dot = A.X + B.U

Y = C. X

The transfer function of this system is

H(s) = C. (sI-A)-1.B                 (1)

H(s), that is calculated in Maple by using the formula (1), is very complex (please see the attached file).

Would you please show me how to find the transfer function of the system?

In addition, how to plot its bode plot?

### Solve state-space system

January 21 2013 by Maple

Hello all,

I have the state-space form of a dynamics sytem:

X_dot = AX+B.U

Y= C X,

The initial conditions of the outputs (Y0) are also given.

A is 7x7 known matrix,

C is 14x7 known matrix,

B = 0;

The problem is that it's too long to write down every equations (14+7 eqns) and variables in "dsolve" function

Would you please show me the shorter way to solve a very large state-space system?

I really appreciate your help.

Why does Maple put space after a new string?

How to prevent Maple from doing that?

### Critical Points

Dear Markiyan Hirnyk

From  Phase-space trajectories i mean below photo which the asterisk arecritical points. but how can i compute the critical points and their nature ( stable , unstable , saddle) with maple ?

Thank for your time
