Download or read book Control of Variable Geometry Vehicle Suspensions written by Balázs Németh and published by Springer Nature. This book was released on 2023-07-08 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a thorough and fresh treatment of the control of innovative variable-geometry vehicle suspension systems. A deep survey on the topic, which covers the varying types of existing variable-geometry suspension solutions, introduces the study. The book discusses three important aspects of the subject: • robust control design; • nonlinear system analysis; and • integration of learning and control methods. The importance of variable-geometry suspensions and the effectiveness of design methods implemented in the autonomous functionalities of electric vehicles—functionalities like independent steering and torque vectoring—are illustrated. The authors detail the theoretical background of modeling, control design, and analysis for each functionality. The theoretical results achieved through simulation examples and hardware-in-the-loop scenarios are confirmed. The book highlights emerging ideas of applying machine-learning-based methods in the control system with guarantees on safety performance. The authors propose novel control methods, based on the theory of robust linear parameter-varying systems, with examples for various suspension systems. Academic researchers interested in automotive systems and their counterparts involved in industrial research and development will find much to interest them in the eleven chapters of Control of Variable-Geometry Vehicle Suspensions.

The book also contains nonlinear constrained tracking control via terminal sliding-mode control and adaptive robust theory, presenting controller design of active suspensions as well as the reliability control of active suspension systems. The target audience primarily comprises research experts in control theory, but the book may also be beneficial for graduate students alike.
Download or read book Axiomatic Design of Customizable Automotive Suspension Systems written by Hrishikesh V. Deo and published by . This book was released on 2006 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of existing suspension systems typically involves a compromise solution for the conflicting requirements of comfort and handling. For instance, cars need a soft suspension for better comfort, whereas a stiff suspension leads to better handling. Cars need high ground clearance on rough terrain, whereas a low center of gravity (CG) height is desired for swift cornering and dynamic stability at high speeds. It is advantageous to have low damping for low force transmission to vehicle frame, whereas high damping is desired for fast decay of oscillations. To eliminate these trade-offs, a novel design for a customizable automotive suspension system with independent control of stiffness, damping and ride-height is proposed in this thesis. This system is capable of providing the desired performance depending on user preference, vehicle speed, road conditions and maneuvering inputs. The design, fabrication and control of the customizable suspension prototype are discussed. The application of variable stiffness and variable ride-height suspension system to achieve improved vehicle dynamics is studied. Application to control of vehicle dynamics parameters required bandwidth and power input beyond the capability of the first prototype.

Download or read book Use of Axiomatic Design Principles to Develop Vehicle Suspension Controls for Variable Stiffness and Ride Height written by Way Luu and published by . This book was released on 2005 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Axiomatic Design principles are used to design a vehicle suspension system. The use of Axiomatic Design helps to guide the design of a decoupled system. The Design Matrix (DM) illustrates the independence among the Functional Requirements (FRs) and the Design Parameters (DPs). The ultimate goal is the design of a fully independent suspension system in which the FRs stiffness, ride height, and damping can be varied as needed. To achieve the three FRs, three DPs are chosen - the volume of an air spring for stiffness, the volume of fluid in a fluid chamber for ride height, and orifice control for damping. This thesis investigates two DPs in depth, the air spring and fluid chamber. The nonlinearity of the air spring is studied and its effect on the system as a whole is simulated in Simulink. Two control systems are proposed in which stiffness and ride height are kept constant. The desired values for stiffness and ride height are predetermined by the user or by an optimization algorithm. The physical design for the control systems is also proposed in this thesis. The design for the air spring system uses an electropneumatic design, and the design for the fluid chamber system uses an electrohydraulic servovalve design.

This book was released on 2020-05-22 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced Seat Suspension Control System Design for Heavy Duty Vehicles provides systematic knowledge of the advanced seat suspension design and control for heavy duty vehicles. Nowadays, people are paying more and more attention to ride comfort and the health of drivers and passengers. This is especially for heavy duty vehicles, where drivers/operators are exposed to much severer vibrations than those in passenger vehicles due to a harsh working environment, operating conditions, and long hour driving, etc. Seat suspension systems can effectively help to suppress the high magnitude vibration transmitted to drivers with relatively simple structure and low cost, and hence are widely adopted in heavy duty vehicles. This book helps researchers and engineers to have a comprehensive understanding of the seat suspension system and to conduct in-depth studies on seat suspension design and control; this book covers a wide range of perspectives about seat suspension design and control methods. Describes the variable damping, variable stiffness, and, especially, variable inertance seat suspensions Provides the advanced and comprehensive knowledge about semi-active vibration control Introduces the multiple-DOF seat suspension Includes the innovative hybrid seat suspension and nonlinear seat suspension All the introduced designs have been prototyped and experimentally validated Provides Matlab Simulation programming codes

Download or read book Vehicle Suspension Systems and Electromagnetic Dampers written by Saad Kashem and published by Springer. This book was released on 2017-09-04 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the development of a new analytical, full-vehicle model with nine degrees of freedom, which uses the new modified skyhook strategy (SKDT) to control the full-vehicle vibration problem. The book addresses the incorporation of road bank angle to create a zero steady-state torque requirement when designing the direct tilt control and the dynamic model of the full car model. It also highlights the potential of the SKDT suspension system to improve cornering performance and paves the way for future work on the vehicle’s integrated chassis control system. Active tilting technology to improve vehicle cornering is the focus of numerous ongoing research projects, but these don’t consider the effect of road bank angle in the control system design or in the dynamic model of the tilting standard passenger vehicles. The non-incorporation of road bank angle creates a non-zero steady state torque requirement.
