A stable design of PI control for DC-DC converters with an RHS zero

Synergetic Control of Power Converters for Pulse Current Charging of Advanced Batteries From a Fuel Cell Power Source

“…1, three such buck converters are connected in parallel to a single fuel cell power source. The active electrical power available from the fuel cell stack is distributed among these three batteries, which can be expressed in (6). (6) where , , and are the electrical power to three charging channels, respectively, and is the electrical power available from the fuel cell stack, and , and are, respectively, efficiencies of three buck converters and they are functions of the power delivered.…”

“…However, design of the controller for power converters in this application presents many challenges since their sources and loads are strongly nonlinear and the system is highly dynamic. Many control methods have been applied to regulate power converters [6]- [10]. The classic proportional-integral control and linear negative feedback control are the most commonly used approaches.…”

Robust Adaptive Wavelet Neural Network Control of Buck Converters

“…From the control viewpoint, the controller design of the switching power supply is an intriguing issue, which must cope with wide input voltage and load resistance variations to ensure the stability in any operating condition while providing fast transient response. Over the past decade, there have been many different approaches proposed for PWM switching control design based on PI control (Alvarez-Ramirez et al, 2001), optimal control (Hsieh, Yen, & Juang, 2005), sliding-mode control (Vidal-Idiarte et al, 2004), fuzzy control (VidalIdiarte et al, 2004), and adaptive control (Mayosky & Cancelo, 1999) techniques. However, most of these approaches require adequately time-consuming trial-and-error tuning procedure to achieve satisfactory performance for specific models; some of them cannot achieve satisfactory performance under the changes of operating point; and some of them have not given the stability analysis.…”

Design of Fractional Order PID controller using Soft computing methods for a Buck-Boost converter

“…Due to this unwanted nonlinear characteristics, the converters requires a controller with a high degree of dynamic response. Recently, the research on the switching control techniques has been highlighted in order to achieve a high-quality power system [1].…”
