Loop model and controlled object model for digitally controlled switching dc-dc converters are set up in this paper, and buck converters stability for both digital control and analog control are comparatively analyzed based on the proposed models. This paper also discusses the presence of one oscillation, called as quasi limit cycle, caused by one additional switching cycle delay in the digital feedback...
Proportional plus derivative controller suffers from non-zero steady-state error due to no integral element. Meanwhile, ignoring ripple in the design process weakens the steady-state performance for switching dc-dc converters. In this paper, a new algorithm is proposed and studied to realize zero steady-state error for proportional plus derivative controller. The proposed algorithm also eliminates...
Digital proportional plus derivative (D-PD) controller with zero steady-state error is introduced for buck dc-dc converters. The proposed D-PD controller decreases the number of look-up tables from three to two, and decreases the adder input from four to three in the compensator circuits in contrast with digital proportional plus integral plus derivative (D-PID) controller. A new technique, called...
