is it possible to convert second or higher order differential equation in s domain i.e. transfer function. directly how?

is it possible to convert second or higher order differential equation in s domain i.e. transfer function...directly

[Azzi Abdelmalek]

What do you mean by directly?

Answer 1

[Azzi Abdelmalek]

Example

Edit

5*d3y-4d2y+10y=20*du+4u

The coefficients of your equation are

D=[5 0 -4 10]
N=[20 4]

% Your transfer function

G=tf(N,D)

[manoj saini]

plz tell me coefficient about D

[Azzi Abdelmalek]

% There was an error,

5*d3y-4dy+10y=20*du+4u      

5 is the coefficient of d3y
0 is the coefficient of d2y
-4 is the coefficient of dy
10 is the coefficient of y

Then

D=[5 0 -4 10]
