Simulink Control Design™ - MathWorks

During simulation, the software linearizes the model using the specified analysis, and

plots the magnitude and phase responses for the resulting linear system.

Save Old Analysis Points When Storing New Analysis Points

Open Simulink model.

mdl = 'scdpwm';

open_system(mdl)

This model is configured with analysis points for finding the combined transfer function of

the PWM and plant blocks.

Create analysis points for finding the transfer function of just the plant model.

io(1) = linio('scdpwm/Voltage to PWM',1,'input');

io(2) = linio('scdpwm/Plant Model',1,'output');

Store the analysis points to the model, and save the previous analysis point configuration.

oldio = setlinio(mdl,io)
