Modelling of magnetorheological semi-active suspension system controlled by semi-active damping force estimator

International Journal of Computer Applications in Technology, 2011
This paper presents the simulation study of magnetorheological semi-active suspension system controlled by a new proposed algorithm. The control algorithm named as Semi-Active Damping Force Estimator (SADE) is proposed to control the operations of the magnetorheological damper.

Semi-active suspension control using "fast" model predictive control

Proceedings of the 2005, American Control Conference, 2005., 2005
The problem considered in this paper is the design and the analysis of a control strategy, for semi-active suspensions in road vehicles, based on model predictive control (MPC) techniques. The computed control law, using predictive techniques aims to optimize, the suspension performance, by minimizing a quadratic cost function while ensuring that the ...

Structural control via semi-active and hybrid control

Proceedings of the 1997 American Control Conference (Cat. No.97CH36041), 1997
A combination of standard active control and low power (often called 'semi-active') devices for control of buildings under seismic excitation is presented. Performance, stability, actuator saturation, and design considerations are among the topics discussed.

Semi-active control devices in structural control implementation

The Structural Design of Tall and Special Buildings, 2005
A semi-active control device for structural control implementations is presented and discussed in this paper. Based on two passive control devices, the mass pump and the hydraulic mass system, a new passive control system, the mass damper pump (MDP), is introduced.

Semi-active control of a thin piezoactuated structure

2000
Vibration damping of a cantilever plate is achieved by using a piezoelectric element simultaneously as passive single-mode device and active broad-band actuator. Control strategies are designed on the basis of a modal model of the coupled electro-mechanical structure. This model is obtained by using a suitable finite-element formulation together with a

Vibration control using semi-active friction damping

1999 European Control Conference (ECC), 1999
Large space structures often consist of truss elements which are connected by bolted joints. The dry friction energy dissipation in these junctions turns out to be a major source of damping. For vibration suppression, the joints are designed such that the normal force to a frictional interface is controlled which improves damping performance.

A new semi-active variational based damping control

2014 IEEE/ASME 10th International Conference on Mechatronic and Embedded Systems and Applications (MESA), 2014
Semi-active damping control of oscillating devices and structures is a challenging field that conjugates a relative actuators simplicity together with the chance of studying new algorithms and system architectures. This paper proposes an overview of the investigation recently developed by the authors in the field of semi-active damping using the ...

Pwm control of semi-active dampers

2022
The positioning and tracking control problems of a Stewart hexapod platform are investigated in the present paper by the use of six optimal semi-active pulse-width modulated brakes. The control in PWM (Pulse Width Modulation) of the damping coefficients of the actuators constitutes a novelty.

A modal control for active/semi-active suspension systems

2007 IEEE/ASME international conference on advanced intelligent mechatronics, 2007
Active/semi-active suspension systems are getting widely accepted for their potential to improve ride comfort of passenger cars with respect to traditional suspension systems. A feedback controller has been designed allowing to control separately the vehicle body motions of heave, pitch and roll taking into account the dynamics of the active/semi ...

"Mitigation of seismic vibration by semi-active control"

2010
Theoretical and practical issues concerning the multi-faceted task of mitigating the latero-torsional seismic response of a prototypal frame structure with asymmetric mass distribution are approached. Chevron braces with embedded magnetorheological dampers acting on the interstory drift are used to provide energy dissipation.
