%% Design Standard-Form PID Controller
% Design a PID controller in standard form for the following plant.
% \textrm{sys}=\frac{1}{{\left(s+1\right)}^3 }
% To design a controller in standard form, use a standard-form controller as the C0 argument to pidtune.

sys = zpk([],[-1 -1 -1],1);
C0 = pidstd(1,1,1); 
C = pidtune(sys,C0)
