Aiming at achieving high robustness performance in Wireless Power Transfer (WPT) systems for moving robot power supply, this paper proposes a H∞ robust control method with multiple parameters that vary randomly, including the mutual inductance, load parameter, and operating frequency. These uncertain parameters make the system control extremely difficult. A composite Upper Linear Fractional Tra...

This paper consist of two sections: control and stabilizing approach for chaotic behaviour of converter is introduced in first section of this paper for the removal of harmonic caused by the chaotic behaviour in current converter. For this work, a Time- Delayed Feedback Controller (TDFC) control method for stability chaotic behaviour of buck converter for switching courses in current control mo...

This paper presents the use of buck converter with Zero Average Dynamics to control speed a permanent magnet direct current motor. For this objective, we consider fourth-order nonlinear model that describes system’s dynamics and tests different scenarios determine how motor responds. The results show robust tracking performance under reference signal controller parameter changes disturbances in...

In this paper, we propose a new technique used to design a robust controller that is not as high-order and complicated as the ones designed by conventional Η∞ loop shaping method. To overcome the problem we proposed an algorithm called Genetic Algorithm (GA) based fixed-structure Η∞ loop shaping control. In the approach, GA is adopted to solve the Η∞ loop shaping design problem under a structur...

The Photovoltaic (PV) system is an eco-friendly renewable energy that integrated with a DC-DC buck-boost converter to generate electrical as per the variations in solar irradiance and outdoor temperature. This article proposes novel Adaptive Fractional Order PID (A-FOPID) compensator self-adjusting fractional orders extract maximum power from stand-alone PV ambient conditions change. reference ...

A novel modified bridge-type dual input DC-DC converter, which is proficient for integrating distinct V-I characteristic sources such as solar-PV, wind, etc., and storages including battery, ultracapacitor, fuel cell, etc., is proposed in this paper. Three modes of operations such as boost, buck, and buck-boost are possible using the same structure of the converter, and the converter can operat...

In this paper, a dc-dc buck converter with digital PI-controlled is analyzed and designed considering all design parameters such as inductance current variation, output voltage ripple etc. The provides stable against to load changes variations. Buck control method relies on mode controlled PWM (Pulse width Modulation) PI (Proportional Integral) controller. criteria, operating selection, suitabl...

This paper shows the results of adding static converters (Boost, Buck and Buck-Boost converters) as an adaptation solution between a PEM Fuel Cell generator and a resistive load in order to study different effects of the converter on the generator performances in terms of voltage and current behavior. The presented results are obtained by simulating the Bond Graph developed model under 20-Sim s...
