On Damping Ratio Estimation in Electronic Semi-active Suspensions
2021 American Control Conference (ACC), 2021In semi-active suspensions, the damping force is not regulated by acting directly on the damping ratio itself, but rather on a related variable, usually a current. Unfortunately, the same current may produce different damping ratios, depending on the status of the shock absorber.

Semi-active suspensions with adaptive capability
Journal of Sound and Vibration, 1995This 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, 1997Abstract 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.

Modeling and Simulation of Semi-Active Suspension for Vehicle
2013In order to shorten the development cycle of semi-active suspension, a batch processing modeling method is studied. 1/4 of the semi-active suspension model is constructed based on AMESim software in this modeling method. Through changing model’s parameters, the simulation results are compared and the system’s performance is analyzed.

Control of Suspensions for Vehicles With Flexible Bodies—Part II: Semi-Active Suspensions
Journal of Dynamic Systems, Measurement, and Control, 1994Two 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

Modelling and Control of a Semi-active Suspension System of Motorcycle
2018 International Conference on Electronics, Control, Optimization and Computer Science (ICECOCS), 2018The 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, 2004Abstract 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 ...

State observers for semi-active suspensions: Experimental results
2014 IEEE Conference on Control Applications (CCA), 2014Semi-active suspension systems aim to improve the stability and comfort of vehicles. Several semi-active suspension control strategies require the vertical velocities; however, the instrumentation of the vehicle normally does not include sensors for these variables, typically only accelerometers are available.

A modal control for active/semi-active suspension systems
2007 IEEE/ASME international conference on advanced intelligent mechatronics, 2007Active/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 ...

A Single-Sensor Control Strategy for Semi-Active Suspensions
IEEE Transactions on Control Systems Technology, 2009The 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.
