Semi-active suspensions with adaptive capability

Journal of Sound and Vibration, 1995
This paper deals with the synthesis of control laws for a 2-DOF model of a vehicle with a semi-active suspension. The suspension system consists of a continuously variable damper and a spring that can vary the suspension stiffness among three different levels.

Development of Semi-Active Truck Suspension

IFAC Proceedings Volumes, 1997
Abstract Within the EC project Copernicus SADTS (Semi-Active Damping of Truck’s Suspension and Its Influence on Driver and Road Loads) the semi-active suspension for Liaz truck prototype is being developed. The objective is to decrease the dynamic road-tyre forces in order to reduce the road damage.

Hybrid active and semi-active seat suspension

2019
In this chapter, a hybrid active and semi-active seat suspension for heavy-duty vehicles is experimentally investigated to fill the performance gap between the two kinds of seat suspensions. An active actuator with low continuous force output, which is insufficient for an active seat suspension system, is applied together with a semi-active MRF damper.

Control of Suspensions for Vehicles With Flexible Bodies—Part II: Semi-Active Suspensions

Journal of Dynamic Systems, Measurement, and Control, 1994
Two methods of control of semi-active suspensions that specifically address the problem of structural vibrations of the vehicle body are considered. These control strategies are based on those developed for active suspension systems in Part I of this study and rely on either modifications of suspension control forces that account for body compliance or

Mechatronics in Japanese Rail Vehicles: Active and Semi-Active Suspensions

IFAC Proceedings Volumes, 2000
Abstract This paper introduces the present state of mechatronics application to the railway vehicle in Japan. The objective mechanisms in the vehicle are classified into five categories such as drive and braking, car body tilting, steering, pantograph and suspension. First, the outline of research and development in each category is described briefly.

Active/semi-active suspension control using magnetorheological actuators

International Journal of Systems Science, 2006
Magnetorheological dampers, which are semi-active devices that use MR fluids to produce controllable forces, can be used as smart actuators to reduce the vibrations of mechanical systems. The advantage of these actuators is the low power input requirements and the high output force they produce.

Modelling and Control of a Semi-active Suspension System of Motorcycle

2018 International Conference on Electronics, Control, Optimization and Computer Science (ICECOCS), 2018
The suspension is one of the most significant components of the vehicle, thus, the performance of vehicles and comfort of the ride are typically affected by the characteristics of the suspension. In addition, this later serves to decrease the vibrations and forces caused by the Irregularities of the road.

Development of a heavy truck semi-active suspension control

Control Engineering Practice, 2004
Abstract The article describes the control design, the development process and the overall performance obtained by a semi-active suspension control for an heavy truck. The control software is developed, debugged and preliminary tuned within a dedicated Matlab/Simulink environment, in time and frequency domain, utilising a simplified vehicle model ...

Design of Semi-active Suspension System

2017
One of the key issues in the design of an active or semi-active suspension system is to identify the appropriate control algorithm. This chapter describes the proposed modified skyhook control closed-loop feedback system and its effectiveness in a semi-active suspension system. The chapter comprises four main sections.

A Single-Sensor Control Strategy for Semi-Active Suspensions

IEEE Transactions on Control Systems Technology, 2009
The topic of this brief is the design and analysis of a control strategy for semi-active suspensions in road vehicles. Currently used closed-loop control strategies (like the Sky-Hook damping) require two sensors for each suspension. Typically, two accelerometers or an accelerometer combined with a stroke sensor are used.
