Hello,

I have to make a project called "Hibrid systems" which would consist in a continuous process controlled by a digital controller. My ideea is to implement a switch mode power supply which would be controlled by a PID implemented on a microcontroller.

Can anyone give me some links to some nice and free PID tunning documentation since I don't have access to control engineering books and also I cannot aford to buy any?

Thank you, Ovidiu
