PDDesign:
-------------------------------------------------------------------------------
Design a PD controller of the form
x = x + ax + bu
y = cx + du
If no outputs are requested then Bode plots for the controller will
be drawn.
-------------------------------------------------------------------------------
Form: [a, b, c, d] = PDDesign( zeta, wN, wD, inr, tSamp, sType )
-------------------------------------------------------------------------------
------
Inputs
------
zeta Damping ratio
wN Undamped natural frequency
wD Derivative term cutoff
inr Axis inertia
tSamp Sampling period*
sType State equation type ('Delta' or 'Z')*
* optional - default is a continuous controller
-------
Outputs
-------
a Plant matrix
b Input matrix
c Output matrix
d Feedthrough matrix
