A non-linear quarter car model is used in this study for developing a control algorithmfor an active suspension system. The control method used, is optimal sliding modecontrol, along with feedback linearization technique for compensating the non-linearaspects of the plant. In addition to the work in recent literature that applies thesecontrol methods, estimation of the static suspension deflection, i.e., vehicle sprungmass is performed. Through simulation results, it is shown that correct information ofvehicle sprung mass, compared to taking it as a constant parameter in control design,improves the performance of the controller. This information, in turn, reduces thesprung mass acceleration level and enhances ride comfort.

Design and simulation of an ABS for an integrated active safety system for road vehicles
Sahin, Murat; Ünlüsoy, Yavuz Samim (2010-01-01)
A design methodology for an anti-lock braking system (ABS) controller for four-wheeled road vehicles is presented. In the study, a flexible approach was adopted considering integration with an integrated active safety system control structure. In the hierarchical control strategy proposed for the ABS controller, a high-level controller, through vehicle longitudinal acceleration-based estimation, determines reference wheel slip values, and a low-level controller attempts to track these reference slip signals...
Design and simulation of an integrated active yaw control system for road vehicles
Tekin, Goekhan; Ünlüsoy, Yavuz Samim (2010-01-01)
In this paper, design methodology and simulation results of an active yaw control system For road vehicles arc presented. The main objectives of the yaw control system arc to estimate the desired yaw behaviour of file vehicle according to the demand of file driver by means of a two degree-of-freedom vehicle model and track this desired yaw rate while considering vehicle steerability parameters. Based on vehicle yaw rate error and vehicle sideslip angle, the controller system applies brake torques to individ...
Analysis and Design of Passive and Active Interconnected Hydro Pneumatic Suspension Systems in Roll Plane
Sağlam, Ferhat; Ünlüsoy, Yavuz Samim (2015-05-19)
In this study, analysis and design of a half car model in roll plane with passive and active unconnected and interconnected Hydro-Pneumatic (HP) suspension systems are made. An interconnection configuration with a connection between the piston side oil volume and rod side oil volume of the right and left suspensions, respectively, is considered. The performance of the active unconnected HP and interconnected HP suspension systems are compared in terms of ride comfort and handling. Nonlinear mathematical mod...
Prediction of automobile tire cornering force characteristics by finite element modeling and analysis
Tönük, Ergin; Ünlüsoy, Yavuz Samim (2001-05-01)
In this study, a detailed finite element model of a radial automobile tire is constructed for the prediction of cornering force characteristics during the design stage. The nonlinear stress-strain relationship of rubber as well as a linear elastic approximation, reinforcement, large displacements, and frictional ground contact are modeled. Validity of various simplifications is checked. The cornering force characteristics obtained by the finite element tire model are verified on the experimental setup const...
Trafik Aglarını Bölüntüleyerek Formel Kontrol Stratejilerinin Üretilmesi
Bardakci, Kemal Cagri; Aydın Göl, Ebru (2017-06-29)
The aim of this paper is to produce control strategies for a large vehicular traffic network model of signalized intersections from Linear Temporal Logic specifications. For this purpose, abstraction and formal control techniques which ensure the correctness of synthesized control strategies are utilized. In addition, in order to solve the scalability problem encountered in formal control of dynamic systems, novel network partitioning methods are developed. The proposed methods guarantee that if each sub-ne...
