Hello, everyone, I m modeling State observer for a quarter car in Matlab for a reduction in vibration I have to assumed some poles for the state feedback gain which is giving me one warning Pole locations are more than 10% in error. Can u help me out what does this warning corresponds to? A = [0 1 0 0 0 0;-320 -18.67 320 18.67 0 0;0 0 0 1 0 0; 68.6 4 -90 -6.1 21.4 2.1;0 0 0 0 0 1;0 0 166.67 -16.67 -3722 -16.67]; B = [0;0;0;0;0;3555.55555]; J = [-60.3958+60.1505i -60.3958-60.1505i -50.6557+16.0469i -50.6557+16.0469i -0.7984 3.9940]; K = acker(A,B,J)

There seems nothing wrong with your inputs. Just I think you missed the point that while you assign two complex conjugate poles to far from dominant region, you forgot to indicate the conjugate of complex number(-50.6557+16.0469i). Use the following J vector and calculate K again.
J = [-60.3958+60.1505i -60.3958-60.1505i -50.6557+16.0469i -50.6557-16.0469i -0.7984 3.9940];
