Mdt2d2x+fvdtdx+kx=f(t)
I have that equation and when I apply laplace transform assuming all initial conditions are zero, I get this.
transfer function =F(s)X(s)=Ms2+fvs+k1
Now I have to find the state-space representation of that.
According to this video, I get this.
X˙=[x1˙x2˙]=[0−k1−fv][x1x2]+[01]f(t)
According to my notes, I get this.
X˙=[x1˙x2˙]=M1[0k1fv][x1x2]+[01]f(t)
Which method is the correct one?
Any help would be appreciated!
