Abstract:
Rollover accidents of heavy vehicles often cause serious consequences both in terms of vehicle and environmental damage as well the loss or injury of drivers, passengers and ordinary civilians. Currently, the active anti-roll bar system is considered as the most effective solution in enhancing vehicle roll stability. In this paper, we firstly investigated the role of a flexible frame of a single unit heavy vehicle in the rollover process. This approach is an important step forward in the research of the active anti-roll bar system. Then, the LQR control method is applied in designing controllers for the active anti-roll bar control system with this frame model. The active torque of the anti-roll bar system is considered as the control signal. The simulation results in the frequency and time domains with a double lane change maneuver show that the vehicle’s roll stability is improved by over 30 % compared to a vehicle using a passive anti-roll bar system.

Abstract:
This paper presents a novel active roll control algorithm for vehicle hydraulic active stabilizer bar system. The mechanical structure and control scheme of hydraulic active stabilizer bar system is detailed. The anti-roll torque controller is designed with “Proportional-Integral-Differential (PID) + feedforward” algorithm to calculate the total anti-roll torque. A lateral acceleration gain and roll rate damping are added into “PID + feedforward” controller, which can improve vehicle roll dynamic response. The torque distributor is introduced based on fuzzy–PID algorithm to distribute the anti-roll torque of front and rear stabilizer bar dynamically, which can improve vehicle yaw dynamics response. The actuator controller is used for realizing the closed-loop control of the actuators displacement and generating the accurate anti-roll torque. The hardware-in-the-loop simulation platform is established based on AutoBox and active stabilizer bar actuators. The hardware-in-the-loop experiment is carried out under typical maneuvers. Experimental results show that the proposed control algorithm improves the vehicle roll and yaw dynamics response, which can enhance the vehicle roll stability, yaw stability, and ride comfort.

Abstract:
The objective of this paper is to design a linear quadratic regulator (LQR) and linear quadratic Gaussian (LQG) controllers for an active anti-roll bar system. The use of an active anti-roll bar will be analysed from two different perspectives in vehicle ride comfort and handling performances. This paper proposed the basic vehicle dynamic modelling with four degree of freedom (DOF) on half car model and are described that show, why and how it is possible to control the handling and ride comfort of the car, with the external forces also control strategies on the front anti-roll bar. By simulation analysis, the design model is validity and the performance under control of linear quadratic regulator (LQR) and linear quadratic Gaussian (LQG) controller are achieved. Both two controllers are modeled in MATLAB/SIMULINK environment. It has to be determined which control strategy delivers better performance with respect to roll angle and the roll rate of half vehicle body. The result shows, however, that LQG produced better response compared to a LQR strategy.

Abstract:
Introduction: Tractor semi-trailer vehicles are playing an increasingly important role in the global freight chain. However, due to the heavy total load and height of the center of gravity, this type of vehicle is often at a higher risk of instability than other vehicles. This paper focuses on improving the vehicle roll stability by using an active anti-roll bar system.
 Methods: The Linear Quadratic Regulator (LQR) approach is used for this purpose with the control signal being the torque generated by the active anti-roll bar system. In order to synthesize the controller, the roll angle of the vehicle body and the normalized load transfer at all axles of the tractor semi-trailer vehicle are considered as the optimal goals.
 Results: The simulation results in time and frequency domains clearly show the effectiveness of the proposed method for the active anti-roll bar system, because the reduction of the desired criterias is about 40% less when compared to a vehicle using the passive anti-roll bar system.
 Conclusions: The effectiveness of the active anti-roll bar system on improving the vehicle roll stability, has been verified in this theoretical study with the LQR optimal controller. This is an important basis for conducting more in-depth studies and future experiments.

Abstract:
The objective of this paper is to optimise the proposed control strategy for an active anti-roll bar system using non-dominated sorting genetic algorithm (NSGA-II) tuning method. By using an active anti-roll control strategy, the controller can adapt to current road conditions and manoeuvres unlike a passive anti-roll bar. The optimisation solution offers a rather noticeable improvement results compared to the manually-tuned method. From the application point of view, both tuning process can be used. However, using optimisation method gives a multiple choice of solutions and provides the optimal parameters compared to manual tuning method.

Abstract:
This paper presents a comparison of performance between a passive and an active anti-roll bar. Off-road vehicles are subject to large input road motion and appreciable lateral forces, making anti-roll bars desirable. A four DOF linear model is used to represent an independent suspension and to design the controller. For every case the performance is evaluated for severe road input perturbation and lateral acceleration. A method is presented to illustrate the compromise between stability and comfort inherent in passive anti-roll bar selection. This method was used to select a realistic anti-roll bar stiffness. The active anti-roll bar was designed using full state feedback optimal controller. A simplification of the active system is proposed to reduce the number of measurements and eliminate the need for an optimal observer. The results show a superior performance in ride and handling for the active controller in the frequency range of interest. The addition of filters is proposed to maximize controller efficiency and to reduce associated problems.

This paper presents the development of a newly developed nonlinear vehicle model is used in the validation process of the vehicle model. The parameters chosen in a newly developed vehicle model is developed based on CARSIM vehicle model by using non-dominated sorting genetic algorithm version II (NSGA-II) optimization method. The ride comfort and handling performances have been one of the main objective to fulfil the expectation of customers in the vehicle development. Full nonlinear vehicle model which consists of ride, handling and Magic tyre subsystems has been derived and developed in MATLAB/Simulink. Then, optimum values of the full nonlinear vehicle parameters are investigated by using NSGA-II. The two objective functions are established based on RMS error between simulation and benchmark system. A stiffer suspension provides good stability and handling during manoeuvres while softer suspension gives better ride quality. The final results indicated that the newly developed nonlinear vehicle model is behaving accurately with input ride and manoeuvre. The outputs trend are successfully replicated.

This paper describes a theoretical study of an active anti-roll bar tilt control system for a railway vehicle. It presents the rationale behind body tilting, the advantages and disadvantages associated with body tilting and the key tilt control system requirements. The paper also describes the control modelling process and presents some simulation results from control system studies. A number of competing control systems have been designed and analysed, including both classical and optimal control strategies. The performance of the control systems for a variety of curves is considered, as well as their response to track irregularities. The results show that all the strategies provide good tilting performance, the optimal control approach being marginally better.

Abstract:
La stabilité en roulis des véhicules est un problème de sécurité très critique, en particulier pour les poids lourds. Actuellement, la plupart des poids lourds sont équipés de systèmes de barres anti-roulis passifs. Malheureusement ceux-ci ne sont pas capables, en général, de surmonter les situations critiques. Cette thèse se concentre sur les systèmes de barres anti-roulis actifs, qui constituent l'approche la plus communément utilisée pour améliorer la stabilité en roulis des poids lourds. Le travail de recherche de cette thèse est divisé en trois parties principales. Dans la première partie, un modèle intégré est développé, comprenant quatre actionneurs hydrauliques commandés par des servo-valves, associés à un modèle linéaire lacet-roulis de poids lourd. Dans la deuxième partie, le système anti-roulis actif est développé suivant deux méthodologies de contrôle dans le cadre LTI: LQR et Hinfty. Dans la troisième partie, une approche LPV, basée sur le maillage, est utilisée pour synthétiser le contrôleur Hinfty/LPV de barre anti-roulis actif avec des fonctions de pondération dépendant de paramètres variants, à l'aide du progiciel LPVTools. Les résultats de simulation dans les domaines fréquentiel et temporel, ainsi que la validation avec le logiciel de simulation TruckSim, montrent que les systèmes de barres anti-roulis actifs sont une solution réaliste et efficace qui améliore considérablement la stabilité en roulis des poids lourds par rapport aux systèmes de barres anti-roulis passifs<br>Vehicle rollover is a very serious problem for the safety of heavy vehicles.

Abstract:
This thesis investigates the use of an active anti-roll bar as a means of improving the handling of an off-road vehicle. The active anti-roll bar consists of a stiff anti-roll bar and a hydraulic actuator at the one end between the anti-roll bar and the rear axle of the vehicle. The system is designed so that the anti-roll bar can be preloaded in both directions by the actuator. The displacement of the hydraulic actuator is close loop controlled to be a function of the lateral acceleration of the vehicle, which is measured by an accelerometer. For this study, full vehicle simulations were done in ADAMS/View to predict the response of the proposed solutions. A Land Rover Defender 110 was used as the test vehicle to verify the results of the simulations. Constant radius tests and the severe double-lane-change manoeuvre, which are standard handling tests, were used to determine the vehicle’s handling performance. Handling performance was quantified by measuring the body roll angle during the manoeuvre and noting the maximum roll angle. The effect of the active anti-roll bar on ride comfort was measured by driving over Belgian paving at a constant speed. The results show that the proposed system reduces the body roll angle to zero up to a lateral acceleration of 0.4 g during steady state handling and provided a 74% improvement in maximum body roll angle during a double-lane-change-manoeuvre at 70 km/h. The system has no detrimental effect on the ride comfort of the vehicle.<br>Dissertation (MEng)--University of Pretoria, 2009.<br>Mechanical and Aeronautical Engineering<br>unrestricted

Abstract:
Active anti-roll bars have recently found greater acceptance among premium car manufacturers and optimal application of this technology has emerged as an important field of research. This thesis investigates the potential of implementing active anti-roll bars in a passenger vehicle with the purpose of increasing customer value. For active anti-roll bars, customer value is defined in terms of vehicle’s ride comfort and handling performance. The objective with this thesis is to demonstrate this value through development of a control algorithm that can reflect the potential improvement in ride comfort and handling. A vehicle with passive anti-roll bars is simulated for different manoeuvres to identify the potential and establish a reference for the development of a control algorithm and for the performance of active anti-roll bars. While ride is evaluated using single-sided cosine wave and single-sided ramps, handling is evaluated using standardized constant radius, frequency response and sine with dwell manoeuvres.The control strategy developed implements a combination of sliding mode control, feed forward and PI-controllers. Simulations with active anti-roll bars showed significant improvement in ride and handling performance in comparison to passive anti-roll bars. In ride comfort, the biggest benefit was seen in the ability to increase roll damping and isolating low frequency road excitations. For handling, most significant benefits are through the system’s ability of changing the understeer behaviour of the vehicle and improving the handling stability in transient manoeuvres. Improvement in the roll reduction capability during steady state cornering is also substantial. In conclusion, active anti-roll bars are undoubtedly capable of improving both ride comfort and handling performance of a vehicle. Although the trade-off between ride and handling performance is significantly less, balance in requirements is critical to utilise the full potential of active anti-roll bars. With a more comprehensive control strategy, they also enable the vehicle to exhibit different driving characteristics without the need for changing any additional hardware.

Abstract:
AbstractChemotherapy has been the backbone for the treatment of recurrent or metastatic nasopharyngeal carcinoma (RMNPC), which remains an incurable disease. Currently the most active area of therapeutic investigations in RMNPC is in immunotherapy, especially after the results of five anti-programmed death-1 (anti-PD-1) antibodies, i.e. pembrolizumab, nivolumab, camrelizumab, toripalimab and tislelizumab, have demonstrated monotherapy objective response rates of 21%–43%. Combinations using anti-PD1/L1 antibodies as backbone to evaluate their additivity or synergy with cytotoxic chemotherapy, molecularly targeted agents, or other immuno-oncology compounds are actively being developed. Besides immune checkpoint blockade, additional ways to modulate the host immune system, such as Epstein-Barr virus (EBV)-directed vaccination against viral antigens (such as EBNA1, LMP1, LMP2) with dendritic cells or peptides, adoptive cell transfer of autologous or HLA-matched allogeneic EBV-specific cytotoxic T lymphocytes, CAR or TCR T-cell therapy, personalized cancer vaccines and oncolytic viruses are being explored. Finally, novel molecularly targeted agents that have entered human testing in RMNPC include apatinib and anlotinib (antiangiogenic agents), MAK683 (an embryonic ectoderm development or EED protein inhibitor), among others. This review provides an update of ongoing clinical trials evaluating these new compounds in RMNPC.

Abstract:
This chapter argues that in France, the application of employment discrimination law is a mixed bag. On the one hand, labour law judges have had some difficulties with interpreting anti-discrimination law, especially when it is based on prohibited grounds linked to the person at work, such as race, and detached from the statutory view of the worker within the scope of applicable law. The need to deepen a factual analysis of context in cases of direct discrimination constitutes a challenge for civil judges more familiar with an approach based on syllogism rather than analogy and comparison. On the other hand, more recently, labour law judges have started resorting to the logic of indirect discrimination in employment which offers original ways to scrutinize collective action, including the right to strike, revealing systemic discrimination.

Abstract:
Sport utility and light-duty commercial vehicles exhibit a higher propensity for rollover during aggressive driving maneuvers, emergency scenarios, and degraded environmental conditions. A variety of strategies have been proposed to reduce vehicle body roll including active suspensions, comprehensive yaw stability systems, and active torsion bars. The active torsion bar systems have recently gained popularity due to their cost effective design and adaptability to existing chassis systems. However, the development of new control algorithms, design of subsystem components, and the evaluation of parameter sensitivity via testing a full scale vehicle is not always practical due to cost and safety concerns. Thus, a modular simulation tool and bench top testing environment is required to facilitate design and performance studies. In this paper, a series of mathematical models will be introduced to describe the vehicle dynamics and the roll prevention system. Representative numerical results are discussed to investigate a vehicle’s transient response with and without an active torsion bar system, as well as the impact of torsion bar and hydraulic component design parameters. Finally, a hardware in-the-loop test environment will be presented.

Abstract:
This paper presents the application of a nominal control design algorithm for rollover prevention of heavy articulated vehicles with active anti-roll bar control. This proposed methodology is based on an extension of Linear Quadratic Regulator (LQR) control for ‘state derivative induced (control coupled) output regulation’ problems. For heavy articulated vehicles with multiple axles, a performance index with Multiple Rollover Indices (MRI) is proposed. The proposed methodology allows us to compare the usefulness of various control configurations (i.e. actuators at different axles of the vehicle) based on the interaction of this control configuration with vehicle dynamics. Application of this methodology to a specific heavy articulated vehicle with tractor semi-trailer shows that a single active anti-roll bar system at the trailer unit gives better performance than multiple-axle actuators at tractor and trailer together with the double lane change maneuver as the external disturbance.

Abstract:
This paper presents some of the work done to model the dynamics of TRW’s semi-active roll control (SARC) actuator. The SARC system is designed to reduce vehicle body roll in a turn and to allow for improved ride and handling while driving straight ahead. The SARC system consists of a hydraulic actuator, vehicle state sensors and an electronic control unit (ECU). The vehicle state sensors and ECU are optional in that existing ESC/VSC elements could be used to control the actuator with the proper control algorithms. The actuator is a compact hydraulic unit consisting of a linear actuator, pressurized reservoir, and associated valves. It mounts between one end of the sway bar and the vehicle suspension, and essentially works to engage or disengage the sway bar. The model was developed to understand and predict the dynamic behavior of the actuator for simulated vehicle inputs. The model was developed in Matlab/Simulink and was validated against experimental test rig data. Model parameters were determined from experimental data and basic engineering principles. This included modeling the dynamics of the seal frictions and the multi-stage control valve. Different vehicle inputs were simulated and the behavior of the actuator under various load regimes was matched to experimental test-rig data. The results show that this model is a reasonably accurate representation of the dynamics of the physical system allowing for usage in controller development and synthesis, and integrating in to vehicle models for integrated software-in-loop (SIL) and hardware-in-loop (HIL) development.

Abstract:
Various active chassis control systems have been developed to improve vehicle handling and stability. Brake-based electronic stability programs and advanced driveline technologies can distribute different wheel torque to all four wheels to regulate vehicle motion. Active front and rear steer systems are widely used to control the vehicle yaw rate and side slip responses. In addition, active anti-roll bars can improve vehicle handling by adjusting roll moment distribution. This paper proposes an integrated chassis control scheme that combines these individual systems using nonlinear predictive control theory. An 8 degree-of-freedom vehicle model is used with a Magic Formula tire model for controller development. The performance of proposed controller is compared to individual control system through simulation and shows significant improvement in vehicle handling.

The controller, consisting of active anti-roll bars, provides the adequate roll moments to the vehicle to improve its performance. The main advantages of fuzzy method are its simplicity, its good performance to control non-linear systems and it is a free-model control.

Abstract:
The reduction of response motion experienced by monohull marine structures through energy dissipation performed by passive stabilisers such as bilge keels is an inexpensive system, when compared to the active motion reduction systems such as active stabilisers or active stabilising fluid tanks. This is the main reason why, despite the obvious advances in motion reduction and control, bilge keels are still designed, produced and fitted to the most recent ships and other marine structures produced. The design philosophy of passive roll stabilisers such as bilge keels has been, and still is, often based on empirical or design codes that define a standard structural arrangement, which is then sized in accordance with the specific characteristics of the vessel. This paper discusses the main internal structural arrangement configurations which may be adopted for bilge keel design, highlights the critical details which particular attention has to be paid to, presents the main steps involved in the sizing of the structural elements, and evaluates the more advantageous configurations with respect to performance vs. production cost. In what respects internal arrangement, the widest possible range of possibilities is considered, from the simple and fairly inefficient flat bar configuration, to the highly complex high performance diaphragm based designs.
