Fast and robust voltage control of DC–DC boost converter by using fast terminal sliding mode controller

Abstract

In this study, a fast terminal sliding-mode control scheme is proposed as a new approach for the voltage tracking control of the DC-DC boost converter affected by disturbances, such as the variations in the input voltage and the load resistance. Some experiments are performed on a test bench to show the effectiveness of the proposed approach. The fast reference tracking capability with small overshoot and robustness to the disturbances of the designed controller is verified by the experimental results. Moreover, the results demonstrate that the proposed controller has a better performance related to conventional sliding mode and proportional-integral controllers in terms of the settling time and robustness to the disturbances.

An immersion and invariance based input voltage and resistive load observer for DC–DC boost converter

“…Nowadays, DC-DC power converters are employed to increase or decrease output voltage in various applications of power electronic. Providing reliable voltage with acceptable regulation is one of the topics studied by researchers in recent years [1,2]. One of the most widely used converters in this field is DC-DC boost converter that is used to regulate the output voltage of systems requiring higher voltage levels.…”

“…Another group of controllers that do not need exact information of mathematical model of system are intelligent controllers such as neural network [11] or fuzzy controllers [12]. However, because the use of these types of controllers requires considerable memory and computational efforts, their application in power electronics industry has not been welcomed [1]. Therefore, different studies have tried to eliminate mentioned weakness applying nonlinear controllers.…”

Design and implementation of an improved sliding mode controller for maximum power point tracking in a SEPIC based on PV system

“…In some nonlinear systems, a linear controller such as the proportional‐integral (PI), is used . Nevertheless, these MPPT techniques are based on a linearization of the system in proximity of the operation point, while the switching signals of power electronic converters and PV systems are fundamentally nonlinear . In the work proposed by Trejos et al, the input current of the converter is regulated by a linear control of the inductor current, which is based on the linearization of the PV model.…”

“…11 Nevertheless, these MPPT techniques are based on a linearization of the system in proximity of the operation point, while the switching signals of power electronic converters and PV systems are fundamentally nonlinear. [12][13][14] In the work proposed by Trejos et al, 15 the input current of the converter is regulated by a linear control of the inductor current, which is based on the linearization of the PV model. This controller cannot guarantee the proper performance of the system at all PV operating points, because the operating point changes with load variations and environmental conditions.…”

PI kontrolcü tabanlı yeni bir kontrol yapısının yükseltici DA-DA çevirici için tasarımı

“…Klasik PI ve PID kontrolcü türlerinin kullanıldığı geri beslemeli kontrol yapısı yükseltici çevirici kontrolünde sıklıkla uygulanmaktadır [9][10][11][12]. PI ve PID kontrolcülerin çevirici cevabı açısından yeterli olmadığı öngörülen birçok çalışmada, yükseltici çevirici kontrolü için modern kontrol tekniklerinden olan Kayan Kip Kontrolcü tabanlı kontrol tekniği başarılı bir şekilde uygulanmıştır [13,14]. Mevcut literatürde bahsi geçen kontrolcülerin tasarımı, yükseltici çeviricinin belli çalışma noktaları için elde edilen matematiksel model için tasarlanmaktadır.…”
