Simulink Control Design™ - MathWorks

Simulate the response of the continuous model:

sim(mdl_continuous);

T1 = simout.time;

Y1 = simout.signals.values;

Plot the simulation of both the discrete and continuous models. Note that the response

becomes more oscillatory as the sample time is increased.

plot(T1,Y1,'k',T2,Y2,'r',T3,Y3,'g')
