syms s ka = 1b = -5/sK = a + b;G = 6*s + 12/s^3 + 8*s^2 + 19*s + 12;F = 1;R = 1/s^2;Error = (K*G/(1+K*G*F));ssE = limit(s*Error,s,0);
I trying to churn a ramp response figure with this code. I remove R from Error eqn as to find feedback response. I type in " figure(1);step(Error/s) " to create figure but error keeps prompting "not enough input arguements".
Could use some advice on this?
Thnk!
