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.

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.

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 ...

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 ...

Analysis of a semi-active MR-damper with hysteretic and asymmetric properties
Proceedings of the 2003 American Control Conference, 2003., 2004A generalized model is proposed to characterize the hysteretic damping properties of a magneto-rheological (MR) fluid damper, which yield asymmetric force in compression and rebound. The proposed nonlinear damper model incorporating applied current, and magnitude and frequency of the response, is employed within a two-DOF "quarter-car" model to ...

Control of Structure with Semi-active Friction Damper by Intelligent Algorithm
2006 IEEE International Conference on Fuzzy Systems, 2006Based on the fuzzy logic of the Takagi-Sugeno (T-S) model and the bang-bang control law, a fuzzy sub-optimal bang-bang control method is presented in this paper. Genetic algorithm is used to determine the optimal control force in the T-S model. The relative performance index is utilized as the objective function. A building structure with a semi-active
