Adding Delays to Linear Models

You can add time delays to linear models by specifying an input or output delay when building a model. For example, to add an input delay to the DC motor, use this code.

• sys_tfdelay = tf(1.5, [1 14 40.02],'inputdelay',0.05)
  

The Control System Toolbox constructs the DC motor transfer function, but adds a 0.05 second delay.

• Transfer function:
                        1.5
  exp(-0.05*s) * ------------------
                 s^2 + 14 s + 40.02
  

For a complete description of adding time delays to models, see Time Delays online under "Creating and Manipulating Models."
