Simulink Control Design™ - MathWorks

To verify that the notch filter performs as expected, evaluate the total compensator C and

the open-loop response L and compare the Bode responses of G, C, L:

% Get tuned block values (in the order blocks are listed in ST2.TunedBlocks)

[g,LL,N] = getBlockValue(ST2,'Gain','Leadlag','Notch');

C = N * LL * g;

L = getLoopTransfer(ST2,'Notch',-1);

bode(G,C,L,{1e1,1e3}), grid
