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 individual wheels in order to create a yaw moment. thus maintaining file desired vehicle behaviour. The control system is based on fuzzy logic control and consists of a two-level controlling scheme: the high-level controller deals with the yaw rate control and vehicle sideslip angle limitation, while the low-level controller calculates and applies the appropriate brake torques to the appropriate wheels requested by the high-level controller for yaw moment generation. An eight degree-of-freedom vehicle model is used to represent the real vehicle in the simulations. Results are compared with those of similar Studies in the literature and the observed differences are discussed.

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, Modeling, and Control Allocation of a Heavy-Lift Aerial Vehicle Consisting of Large Fixed Rotors and Small Tiltrotors Ozdogan, Gokhan; Leblebicioğlu, Mehmet Kemal (2022-02-01) In this article, we propose an unconventional heavy-lift aerial vehicle (HLAV), present the design and its control allocation analysis, and prove the concept by the demonstration of the experimental test prototype in the outdoor environment. We aim for a mechanically robust and simple vehicle design that efficiently performs heavy lifting compared to other common aerial vehicles under certain width constraints, without using a complex swashplate mechanism. The HLAV performs the task of carrying the main loa...
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...
design and implementation of a two-axes linear positioning system for rapid prototyping applications Yazıcıoğlu, Faruk; Söylemez, Erses; Department of Mechanical Engineering (2007) In this study, a two axes linear positioning system for testing and applying different rapid prototyping techniques was designed and manufactured. A cable/ pulley mechanism is utilized in the system for transmitting motion from motors into linear motion. Use of a cable/ pulley mechanism overcomes the problems resulting from the utilization of conventional drive systems like ball screws and decreases the overall cost of the system. The carriage elements of both axes were designed and manufactured by using in...
Design of an Optimal Sliding Mode Controller for an Active Suspension Considering Non-linear Quarter Car Model Sadeghi-Khaneghah, Farshid; Bayar, Kerem; Department of Mechanical Engineering (2020-7-26) 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 ofv...
