in this paper, the 1/4 vehicle model have been simulated. the vehicle body acceleration using optimal control has been optimized. the vehicle ride comfort is achieved by using robust control, and it has been compared with optimal control. the active suspension can help the vehicle to have a good dynamic behavioral. in this paper, two degrees of freedom dynamic vibration model of a general vehic...

In the last few years, different linear and non-linear control techniques have been applied by many researchers on the vehicle suspension system. The basic purpose of suspension system is to improve the ride comfort and better road handling capability. Therefore, a comfortable and fully controlled ride can not be guaranteed without a good suspension system. The suspension system can be categori...

In order to address the problem that traditional passive suspension damping parameter cannot be adjusted which makes it difficult to improve vehicle ride comfort and handling stability, the paper proposes use of controllable magneto-rheological dampers in replace of passive dampers to establish semi-active suspension based on magneto-rheological dampers. By designing magneto-rheological damper ...

Abstract: This paper proposes a nonlinear backstepping control strategy to improve the inherent tradeoff between ride comfort of passengers and suspension travel. Passenger comfort in ground vehicles usually depends on a combination of vertical motion (heave) and angular motion (pitch and roll). Suspension travel means the space variation between vehicle body and tires. Our active suspension de...

In recent years, motor vehicles industry has shown a tendency of replacing electromechanical components by mechatronic systems with intelligent and autonomous properties. The integration of hardware components and implementation of advance control function characterize this replacement. In this paper, we have applied the system approach and system engineering methods in the initial phase of veh...

Suspension system of a vehicle is used to minimize the effect of different road disturbances for ride comfort and improvement of vehicle control. A passive suspension system responds only to the deflection of the strut. The main objective of this work is to design an efficient active suspension control for a full car model with 8-Degrees Of Freedom (DOF) using adaptive soft-computing technique....
