Nonlinear Robust Power Control of Uncertain DC-DC Converter with Bilinear Dynamics

Robust optimal control of bilinear DC–DC converters

This paper addresses the control problem of dc–dc converters. The control law synthesis considered here exploits the potential of LMI-based control approaches, which allow to cope with model uncertainty, disturbances and bilinearities to synthesize simple state-feedback controllers with a priori guarantee of stability in a large domain of initial and operating conditions. The aim of the paper i...

Robust Time-Delay Control for the DC-DC Boost Converter

Nonlinear Control for Bidirectional Power Converter in a dc Microgrid

Some comparative studies of several nonlinear control techniques applied to dc-dc power converters are developed in this paper, like for instance the Immersion & Invariance, Passivity-Based Control, Feedback Linearization and the Sliding-Mode Control. All these different control strategies are used to drive dc-dc power converters in a dc microgrid. The load, modeled as a Constant Power Load typ...

Nonlinear control applied to a dc-dc power converter and the load sharing problem in a dc microgrid ?

The purpose of this paper is to apply the Immersion & Invariance and Passivitybased Control to a dc-dc power converter driving a nonlinear load. Experimental results are shown in order to evaluate the performance of the proposed control techniques. Another goal is to find a model for a dc microgrid (load sharing problem) and to show some stability issues.

Flexible Control of Power Flow in Multiterminal DC Grids Using DC-DC Converter

This paper proposes an efficient control framework that utilizes de-de converters to achieve flexible power flow control in multiterminal de (MTDC) grids. The de-de converter employed in this paper is connected in cascade with the de transmission line, and is therefore named cascaded power flow controller (CPFC). In this paper, a two-layer control strategy is developed for the operation and con...
