Semi-Active Steering Damper Control in Two-Wheeled Vehicles
IEEE Transactions on Control Systems Technology, 2011This work presents the design of innovative control strategies for a semi-active steering damper aimed at improving two-wheeled vehicles steering stability by controlling the weave and wobble modes. The proposed control strategies arise from a parallelism between steering and vertical dynamics of a motorcycle.

Semi-active Dampers for Multiple Pantograph Operation
2020Multiple pantograph operation is an unfavourable condition for current collection, since the trailing pantograph is subjected to high vibrations and elevated contact force variations, due to the perturbation induced on the overhead line by the leading pantograph.

A new concept of semi-active suspension with controllable damper and spring
2009 European Control Conference (ECC), 2009The problem considered in this paper is the design and analysis of implementable architectures for semi-active suspensions characterized by a regulation of both damping and stiffness coefficients. The first contribution of this paper is the introduction of a suspension architecture that makes possible the emulation of the behavior of an ideal ...

Semi-active hydropneumatic spring and damper system
Journal of Terramechanics, 1998This paper is concerned with the development of a semi-active hydropneumatic spring and damper system, comprising of a two state hydropneumatic spring and a two state hydraulic damper. The system was specifically developed to improve the ride comfort and handling of large off-road vehicles. The suspension requirements for good ride comfort and handling

Control Concepts of Semi-Active Friction Dampers
Volume 1: 22nd Biennial Conference on Mechanical Vibration and Noise, Parts A and B, 2009Reduction of structural vibrations is of major interest in mechanical engineering for lowering sound emission of vibrating structures, improving accuracy of machines and increasing structure durability. Besides design optimization and passive damping treatments, active structural vibration control can be applied to reduce unwanted vibrations.

Electrorheological dampers and semi-active structural control
Proceedings of 1994 33rd IEEE Conference on Decision and Control, 2002Electrorheological (ER) fluids have a number of properties that make them attractive for use in fluid-filled dampers. Our interest is in the use of such dampers for semi-active structural control. This paper provides an introduction to this subject, with emphasis given to control of large structural systems such as buildings and bridges when excited by

Experimental Evaluation of a Semi-Active Friction Damper
Elasto-Impact and Friction in Dynamic Systems, 1996Abstract Semi-active control of friction dampers has been proposed to improve the energy dissipation characteristics of passive friction dampers and to broaden the areas of application in which they can successfully be used. In this paper, we implement a control law which maximizes energy dissipation in an instantaneous sense by ...

Neuro-Fuzzy Control for Semi-active Dampers
2014In many engineering applications, vibrations are a very typical type of disturbances. Due to this, different technologies have been developed in order to reduce (or ultimately eliminate) the potential negative impact they may incur on mechanical systems.

Performance of a Semi-Active Damper for Heavy Vehicles
Journal of Dynamic Systems, Measurement, and Control, 1998This paper describes the development, modeling, and testing of a prototype, continuously variable semi-active damper for heavy vehicles. A simple proportional valve is used to generate the variable damping coefficient and the detrimental effects of the oil flow forces acting on the valve spool are studied.

Semi active tunable mass damper for helicopters
SPIE Proceedings, 2017Helicopters are among the most complex machines ever made. While ensuring high performance from the aeronautical point of view, they are not very comfortable due to vibration mainly created by the main rotor. Traditionally this problem is solved by mounting several TMD inside the helicopter, each tuned to the frequency of the disturbance the main ...
