Abstract :
This paper presents a methodology to design a PID Digital Compensator for digital controller power electronics systems. This method is base on direct digital design and use on digital controller buck dc-dc converter. Crossover frequency and phase margin of close-loop system can be set by this method, and the integration coefficient in digital compensator set by this method can be avoid one of the LCO(Limit Cycle Oscillation) condition.
