Design of an improved PID controller for DC/DC boost pourer converter with inductor resistance under load variation

부하변동과 인덕터 저항을 고려한 DC/DC 승압 컨버터의 개선된 PID 제어기 설계

This paper presents a new PID controller for a DC/DC boost converter model that has a parasitic inductor resistance. In order to maintain the robust output regulation property under load variations the proposed controller is designed by using an additional state variable developed via a parallel-damped passivity-based control approach. Simulation results using Matlab/Simulink SimPowerSystems compare the performances of the proposed controller with a conventional PI controller for reference step changes and load uncertainties.
