i am using the SISO design tool (matlab function rltool) to design a compensator. in my frequency response, i have a requirement for a pole at the origin.
The pole is in the form of omega/s, which can be written as 1/(s/omega). However, i cannot plot anything like this in the SISO design tool.
How can i plot this?

Pole at the origin is an integrator. To add it, right-click on the plot, and select "Add Pole/Zero" -> Integrator.
To change the gain (omega), select "Compensator Editor" tab in the "Control and Estimation Manager" window, and edit the gain in the Compensator dialog.
