A MATLAB script plotting the asymptotic Bode plot of a given LTI system. There are a couple of other scripts on File Exchange with errors accounted for here.
The function can receive as an input a tf, zpk, ss or a symbolic expression representing a rational function.
* The model can be improper, e.g., calling asymp_bode(tf([1 1],[0 1])) will plot the expected bode diagram.
* Time delays, non minimum-phase system and poles/zeros at the origin are accounted for.
* The script decomposes the individual phase and gain plots of each element and sums them together.
* Pure imaginary poles and zeroes are currently not supported
