How do you create a lead compensator in Matlab?

In MATLAB, a phase-lead compensator C(s) in frequency response form is implemented using the following code (where a and T are defined). s = tf('s'); C_lead = (1+a*T*s)/(1+T*s); We can then interconnect it with a plant P(s) using the following code.

What does a lead compensator do to a Bode plot?

Lag compensators are intended for improving steady state response - in other words, we are focused on tuning the DC gain in the magnitude plot. Conversely, lead compensators are trying to meet transient performance specifications, which means that they need to change the phase diagram to add phase margin.

How do you plot a Bode diagram in Matlab?

h = bodeplot( sys ) plots the Bode magnitude and phase of the dynamic system model sys and returns the plot handle h to the plot. You can use this handle h to customize the plot with the getoptions and setoptions commands.
