%% Extract Coefficients from 2-DOF PI Controller Array % Typically, you obtain an array of controllers by using |pidtune| on an % array of plant models. For this example, create an 2-by-3 array of % 2-DOF PI controllers with random values of |Kp|, |Ki|, and |b|. %% % Copyright 2015 The MathWorks, Inc. rng('default'); C2 = pid2(rand(2,3),rand(2,3),0,0,rand(2,3),0); %% % Extract all the coefficients from the array. [Kp,Ki,Kd,Tf,b,c] = piddata2(C2); %% % Each of the outputs is itself a 2-by-3 array. For example, examine |Ki|. Ki %% % Extract only the coefficients of entry (2,1) in the array. [Kp21,Ki21,Kd21,Tf21,b21,c21] = piddata2(C2,2,1); %% % Each of these outputs is a scalar. Ki21
