Analysis of instability causes in the bi‐dc converter and enhancing its performance by improving the damping in the IDA‐PBC control

IET Generation, Transmission & Distribution, 2021
The poor damping of bidirectional dc (bi‐dc) converter caused by constant power load makes power system prone to oscillation, and non‐minimum phase characteristic also jeopardises voltage stability.

IDA-PBC Control of an Underactuated Underwater Vehicle

Revista Iberoamericana de Automática e Informática Industrial RIAI, 2017
This paper presents an IDA-PBC (Interconnection and Damping Assignment-Passivity Based Control) for underactuated undewater vehicle control, which it has more degree of freedom than actuators. In this proposal, six degree of freedom and only four propels

Adaptive and Nonlinear Control Techniques Applied to SEPIC Converter in DC-DC, PFC, CCM and DCM Modes Using HIL Simulation

Energies, 2018
In this paper, we propose adaptive nonlinear controllers for the Single-Ended Primary Inductance Converter (SEPIC). We also consider four distinct situations: AC-DC, DC-DC, Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM).
