“…This system works electronically and can be controlled electronically according to the road condition in many modern vehicles, such as BMW, Mercedes-Benz and Volvo [20]. The Simulink/Matlab program has the ability to simulate and separate unspring mass from spring mass and make its power which focuses on suspension system to suit road disorder [21].The amount and power created by actuator on their effectiveness to reduce vibration resulting from the different road roughness, how actuator (PID) works on active suspension system and the influence of power on basic and rear wheels and passengers presented in [22].…”

A Suspension system can be defined as the mechanism that physically separates the car body from the car wheels. The purpose of any suspension system is to increase the ride comfort, road handling and stability of closed loop system. The suspension design must be compensate the effect of conflicting criteria of road holding, load carrying and passenger comfort. An active suspension system has been proposed. A quarter-car two degree-of-freedom (2DOF) system is designed and constructed to simulate the actions of an active quarter car suspension system. White noise input is introduced to a given system to expressed unpaved road and both step input and sine wave input are studied as well. The control strategy is based on two degree of freedom PID controller. (MATLAB/ Simulink) is used to verify the proposed algorithm. The comparison between the passive and active suspension and the results obtained from a range of road input simulations in the proposed algorithm shows the effectiveness of the proposed algorithm and best results are obtained.

“…This is because active systems offer additional functionalities and therefore enlarge the full driving dynamics potential of a vehicle by employing different types of actuator, such as magnetorheological actuators and hydraulic actuators. [1][2][3][4][5][6][7][8][9][10][11] Compared to other active and semi-active suspension systems, vehicle height adjustment is one of the salient features of electronically controlled air suspension (ECAS) systems. Many approaches to the vehicle height controller design for ECAS have been proposed.…”

This paper proposes a mode control algorithm of electro-mechanical suspension for vehicle height, attitude control and improvement of ride quality. The proposed control algorithm consists of mode selector, upper-level and lower-level controllers, and suspension state estimator. The mode selector determines the present driving mode using vehicle signals, such as longitudinal speed, steering wheel angle, accelerator pedal position, brake pedal position and vertical acceleration of wheels. The upper-level controller determines the desired suspension state using the present driving mode. The lower-level controller derives the desired stroke speed of the actuator in each suspension by linear quadratic control theory. The suspension state estimator has been designed using accessible sensor measurement by discrete-time Kalman filter theory. The control and estimation algorithms have been developed based on a novel reduced-order vehicle model that includes only the vehicle body dynamics. The model enables the observer to completely remove the effect of unknown road disturbance on the estimation error. The performance of the proposed control algorithm has been evaluated via computer simulation study. The simulation results show that the proposed control algorithm is effective at controlling the electro-mechanical suspension systems. The paper also shows that the considered actuator is suited for vehicle height and levelling control, but not for improvement of ride comfort, due to voltage input constraints.

“…In general, there are three important issues: passenger comfort (ride quality), handling (road-holding) and suspension travel (stroke limits) control. Although multi-objective controller synthesis is a trend in semi-active suspension design (see in Lu and DePoyster (2002), Güvenc et al (2006) and Poussot-Vassal et al (2008)), it is true that the most important and basic issue to be studied is the passenger comfort. One of the first comfort-oriented control methods, which has been successfully applied in commercial vehicles, is the Skyhook control proposed by Karnopp et al (1974).…”

The paper presents an extension of the mixed Sky-hook and ADD to Magneto-Rheological dampers. Firstly, a semi-active automotive suspension equipped with a nonlinear Magneto-Rheological damper is introduced. The interest of this nonlinear model is that the bi-viscous and hysteretic behaviors of MR dampers can be taken into account in the controller design. Hence, the designed controller is more adaptive with real MR dampers. Finally, the new mixed Sky-hook and ADD algorithm for MR dampers is proposed to enhance the passenger comfort. The performances of the proposed control method are then analyzed, based on simulations on a nonlinear vehicle model. The results show that the Mixed Sky-Hook and ADD can be successfully extended to Magneto-Rheological dampers.
