%% Create Uncertain LTI Dynamics % You can create a 1-by-1 (scalar) positive-real uncertain linear dynamics % element, whose frequency response always has real part greater than -0.5. % Set the |SampleStateDimension| property to 5. Plot a % Nyquist plot of 30 instances of the element. %% % Copyright 2015 The MathWorks, Inc. g = ultidyn('g',[1 1],'Type','Positivereal','Bound',-0.5); g.SampleStateDimension = 5; %% nyquist(usample(g,30)) xlim([-2 10]) ylim([-6 6]);
