Abstract :
This paper describes a digital proportional-integral-derivative (PID) controller technique applied to the DC-DC buck converter. The converter is modelled using a state space averaging technique. Due to the non-linear of the power converter, the PID controller is designed to simplify the compensation of the DC-DC converter. The control algorithm is implemented in digital signal processor (DSP) TMS320F2812. The steady state and dynamic response performances of the controller are demonstrated. Experimental results are provided to demonstrate the effectiveness of the design.
