Passivity-based boundary control for vibration suppression of the shear beam

Advances in Mechanical Engineering, 2022
In this paper, the passivity-based boundary controller for the vibration suppression of the flexible beam is studied. The undamped shear beam model is used as a beam model.

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).

Control of Haptic Systems Based on Input-to-State Stability

IEEE Access, 2022
Discretization of signals often generates additional energy in the haptic systems, and makes them unstable. The currently popular controls based on the passivity stabilize the systems by limiting the rendered force of the haptic systems so that the ...

Robust Passivity Cascade Technique-Based Control Using RBFN Approximators for the Stabilization of a Cart Inverted Pendulum

Mathematics, 2021
This paper proposes a novel passivity cascade technique (PCT)-based control for nonlinear inverted pendulum systems. Its main objective is to stabilize the pendulum’s upward states despite uncertainties and exogenous disturbances.

Passivity Analysis of Nonlinear Euler-Bernoulli Beams [PDF]

Modeling, Identification and Control, 2002
The Lagrangian equations for distributed-parameter systems based on Hamilton's principle are developed. These equations are subsequently used to derive nonlinear models for beams. The passivity properties of the flexible mechanical systems based on their

A robust passivity based control strategy for quasi‐resonant converters

IET Power Electronics, 2021
This paper presents a robust passivity‐based control (RPBC) strategy for half‐wave zero‐voltage switching quasi‐resonant (HW‐ZVS‐QR) buck and boost type converters. The proposed controller is based on energy shaping and damping injection.

Human Modeling and Passivity Analysis for Semi-Autonomous Multi-Robot Navigation in Three Dimensions

IEEE Open Journal of Control Systems
In this article, we study a one-human-multiple-robot interaction for human-enabled multi-robot navigation in three dimensions. We employ two fully distributed control architectures designed based on human passivity and human passivity shortage. The first
