From: Susan on 12 Apr 2010 19:50 I have a TF which has a numerator larger than my denominator. I used the following code to determine the remainder and quotient. In the end I want a plot of the remainder divided by the original denominator with a y-shift by the quotient. v=[0.1741 137.8 511.8 888.8 662.1 166.9 0 0];%numerator of original TF u=[0.002721 2.147 33.96 75.43 89.24 0 0 0];%denominator of original TF [q,r] = deconv(v,u); %q = 63.9838 %showing the quotient %r = [0 .4 -1661.1 -3937.5 -5047.8 0166.9 0 0] %remainder t=1:1:1000; Duty_sys=tf(r, u) [Y,T] = step(Duty_sys,t) plot(T,Y+q);%I'm shifting the plot up by the value of the quotient. I'm not getting the plot my advisor expected. My function is a ramp, but my advisor is saying I should be getting an "s-shaped" curve. Is this code the right way to divide a numerator by a denominator to get a remainder and quotient? |
