Active Anti-Roll Bar Control Design for Heavy Vehicles

by Vu Van Tan Olivier Sename Peter Gaspar Trong Tu Do

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.

Active Cancellation of Probing in Linear Dipole Phased Array (SpringerBriefs in Electrical and Computer Engineering)

by Hema Singh Rakesh Mohan Jha N. Bala Ankaiah

In this book, a modified improved LMS algorithm is employed for weight adaptation of dipole array for the generation of beam pattern in multiple signal environments. In phased arrays, the generation of adapted pattern according to the signal scenario requires an efficient adaptive algorithm. The antenna array is expected to maintain sufficient gain towards each of the desired source while at the same time suppress the probing sources. This cancels the signal transmission towards each of the hostile probing sources leading to active cancellation. In the book, the performance of dipole phased array is demonstrated in terms of fast convergence, output noise power and output signal-to-interference-and noise ratio. The mutual coupling effect and role of edge elements are taken into account. It is established that dipole array along with an efficient algorithm is able to maintain multilobe beamforming with accurate and deep nulls towards each probing source. This work has application to the active radar cross section (RCS) reduction. This book consists of formulation, algorithm description and result discussion on active cancellation of hostile probing sources in phased antenna array. It includes numerous illustrations demonstrating the theme of the book for different signal environments and array configurations. The concepts in this book are discussed in an easy-to-understand manner, making it suitable even for the beginners in the field of phased arrays and adaptive array processing.

Active Control of Bidirectional Structural Vibration (SpringerBriefs in Applied Sciences and Technology)

by Wen Yu Satyam Paul

This book focuses on safeguarding civil structures and residents from natural hazards such as earthquakes through the use of active control. It proposes novel proportional-derivative (PD) and proportional-integral-derivative (PID) controllers, as well as discrete-time sliding mode controllers (DSMCs) for the vibration control of structures involving nonlinearities. Fuzzy logic techniques are used to compensate for nonlinearities. The first part of the book addresses modelling and feedback control in inelastic structures and presents a design for PD/PID controllers. In the second part, classical PD/PID and type-2 fuzzy control techniques are combined to compensate for uncertainties in the structures of buildings. The methodology for tuning the gains of PD/PID is obtained using Lyapunov stability theory, and the system’s stability is verified. Lastly, the book puts forward a DSMC design that does not require system parameters, allowing it to be more flexibly applied. All program codes used in the paper are presented in a MATLAB®/Simulink® environment. Given its scope, the book will be of interest to mechanical and civil engineers, and to advanced undergraduate and graduate engineering students in the areas of structural engineering, structural vibration, and advanced control.

Active Disturbance Rejection Control: From Principles to Practice (Control Engineering)

by Gernot Herbst Rafal Madonski

This open access text offers the first comprehensive introduction to the fundamental principles and practical implementation of Active Disturbance Rejection Control (ADRC). Drawing on their years of experience in both research and industry, the authors have designed the text to be accessible to readers at any level of knowledge and experience with ADRC. Multiple entry points and paths through the text are defined so that it can be easily adapted to their specific needs. Part I covers the theoretical foundations of ADRC, giving readers the basic information in a self-contained, tutorial style. Emphasis is placed on first developing an intuition for ADRC through illustrative examples inspired by real control problems. The main concepts are then introduced and explored in a more formal and concise manner using standard control-domain-related terminology. Part II demonstrates methods for applying ADRC in practice through software-based implementation. Utilizing laboratory testbeds to mimic real control problems from process and control areas, the authors illustrate the use of software through both model-based environments - including MATLAB/Simulink - and low-level C programming language. Common issues that one can encounter when implementing controllers in the real world are also examined, and specific solutions to these problems are offered that retain the simplicity of ADRC. This book can be used as a textbook, handbook, or reference manual, and through its many entry points, can be easily picked up by students, practitioners, and scientists. Having in mind its introductory nature, the prerequisites for studying the considered subject are intentionally not very strict. Readers should have at least basic knowledge of systems and controls, as well as an understanding of core mathematical concepts of calculus, linear algebra, and differential equations.
