About this book

This book provides a comprehensive overview of active anti-roll bar systems on heavy vehicles as one of the most effective solutions for improving the roll stability of these vehicles. Due to the characteristics of these vehicles with heavy loads and high center of gravity, the possibility of roll instability occurs frequently and causes serious consequences for human life, vehicles, and traffic infrastructure. The book gives readers an in-depth survey of the roll instability characteristics of heavy vehicles such as single-unit trucks with rigid and flexible frames, and tractor semi-trailers. It then introduces an active anti-roll bar system, the electro-hydraulic actuators which use control methods such as LQR optimal and H∞ robust controller design. This work introduces a new control method, which is a combination of robust control with the linear parameter varying system (H∞/LPV). The validation of the new hybrid method is carried out using the nonlinear truck model from the TruckSim® software to assess the roll stability of heavy vehicles in order to limit the rollover accident. A number of examples are provided to illustrate the research results, which helps the readers have a practical and easy approach that can be applied to other active anti-roll bar systems for most forms of transport vehicles in general. This book caters to academics and practitioners who are interested in active anti-roll bar systems for the typical heavy vehicle available worldwide.

Chapter 1. Introduction and Motivations
Abstract
The active anti-roll bar system plays an important role in improving the roll stability to prevent the vehicle rollover phenomenon, especially for heavy vehicles. The content of this chapter covers the history of its creation and development, from research studies in industry and academia, as well as the roll stability characteristics of automobiles. The rollover phenomenon of heavy vehicles are summarized. Besides, the roll static stability conditions and mechanics of vehicle rollover are mentioned. The researches on the active anti-roll bar system on heavy vehicles including long combination heavy vehicles and single unit heavy vehicle are synthesized according to different research subjects such as: vehicle models, control methods. The synthesis of reputable studies on this system helps readers have a broad view and easily identify the scope of research and real application.

Chapter 2. Vehicle Modelling Using Active Anti-Roll Bar System
Abstract
Automotive models, in general, and heavy vehicle models, in particular, play an extremely important role in understanding the roll stability characteristics of the active anti-roll bar system. The model must clearly satisfy the characteristics of the object and be convenient for research, therefore, this chapter focuses on building Yaw-Roll models of a single unit heavy vehicle and a tractor semi-trailer for two cases with rigid frame and flexible frame. The electronic servo-valve hydraulic actuator model is established and combined with the Yaw-Roll model to create the most realistic research model. The vehicle models are after that rewritten in the state-space representation to evaluate the vehicle roll stability in the frequency and time domains. The characteristics of the passive anti-roll bar are also proposed in this chapter. Proposed models will be used in the design of controllers in the next chapters.

Chapter 3. LQR Optimal Controller Design for Active Anti-roll Bar System
Abstract
The main content of this chapter deals with the design of the optimal controller LQR for the active anti-roll bar system on single unit heavy vehicles and tractor semi-trailers with rigid and flexible frames. First, the theoretical basis of optimal control is synthesized as the basis for the design of the controllers. Then how to design the controllers for each vehicle model with the main goal of improving roll stability and considering the saturation of the actuators. The characteristics of heavy vehicles using active anti-roll bar system are evaluated in the frequency and time domains for comparative analysis. Besides, the efficiency of LQR optimal controllers is also compared with a classical control method, such as PID controllers. The research and survey results show that the ESVH actuator and heavy vehicle models have met the basic requirements in the study of controlling the active anti-roll bar system.

Chapter 4. /LTI Robust Controller Design for Active Anti-roll Bar System
Abstract
Based on the heavy vehicle model, including a single unit heavy vehicle model and a tractor semi-trailer built in the Chap. 2, the robust control method \(H_{\infty }\) for the LTI is used to design the controller for the active anti-roll bar system. First, the previous background studies in this approach are mentioned, and the theoretical basis of the control method is summarized. Then controller \(H_{\infty }\)/LTI is designed for active anti-roll bar system with rigid frames model considering the roll stability and amperage of the ESVH actuators. Meanwhile, the torque of the active system is the signal to be considered when building the controller for the tractor semi-trailer. The effect of this approach is analyzed in detail in the frequency and time domains.

Chapter 5. /LPV Robust Controller Design for Active Anti-Roll Bar System
Abstract
This chapter presents a methodology to design an \(H_{\infty }/LPV\) controller for the active anti-roll bar system. The control-oriented model and the fully integrated single unit heavy vehicle model, including the Yaw-Roll model and four ESVH actuator models are used. The nonlinear model of the vehicle is considered as an LPV model and the controller synthesis method is Grid-based LPV approach based on LPVToolsTM toolbox, where the forward velocity is considered as a scheduling parameter. The effect of the internal oil leakage inside the electronic servo-valve on the closed-loop system is analysed in detail. It shows that the two objectives of enhancing the vehicle roll stability and avoiding the saturation of the ESVH actuators are simultaneously satisfied when the total flow pressure coefficient \(K_{P}\) is limited in a given range.

Chapter 6. Validation of the Active Anti-Roll Bar Control System by Using TruckSim® Software
Abstract
This chapter presents the validation of the \(H_{\infty }/LTI\) and \(H_{\infty }/LPV\) active anti-roll bar controllers proposed in Chaps. 4 and 5 by using the nonlinear vehicle model of \(\text{ TruckSim }\)® software. Three co-simulation programs between Matlab/Simulink and TruckSim are built for three typical heavy vehicles: a tour bus, an LCF truck and a tractor semi-trailer in unloaded and fully loaded states. The main survey scenarios include: Double lane change to overtake, Circular test circuit, Cornering manoeuver, Sine wave steering manoeuver at the different velocities. The results examined with different scenarios and the different forward velocities have clearly shown the effectiveness of improving the roll stability of heavy vehicles. It also shows that the handling performance has improved when the heavy vehicles use the active anti-roll bar system. This is consistent with the results studied in the previous chapters.
