Since the vehicle dynamics is concerned with controllability and stability of vehicle, it is important in design of a ground vehicle. The modeling of the vehicle with the analysis of the dynamic response of the mathematical model have been examined in a large number of investigations. In this paper overview of various works are done. This paper tries to give an idea about the previous researche...

The primary function of a suspension system of a vehicle is to isolate the road excitations experienced by the tires from being transmitted to the passengers. In this paper, we formulate an optimal vehicle suspension design problem with the quarter-car vehicle dynamic model. A new multi-objective genetic algorithm is used for Pareto optimization of a two-degree of freedom vehicle vibration mode...

The paper deals with application of the disturbance-observer (DO) based control to a quarter car active suspension system with uncertain parameters.The DO counteracts disturbances by feedforward compensation computed on the basis of the control input, the state feedback and the nominal system model. The proposed control scheme is verified experimentally on a mechatronic laboratory model. Słowa ...

We approximate the distribution of total expenditure of a retail company over warranty claims incurred in a fixed period [0, T ], say the following quarter. We consider two kinds of warranty policies, namely, the non-renewing free replacement warranty policy and the non-renewing pro-rata warranty policy. Our approximation holds under modest assumptions on the distribution of the sales process o...

Abstract—In this paper, passenger ride comfort issues are studied taking active quarter car model with three degrees of freedom. A hybrid fuzzy – PID controller with coupled rules (HFPIDCR) is designed for vibration control of passenger seat. Three different control strategies are considered. In first case, main suspension is controlled. In second case, passenger seat suspension is controlled. ...

Abstract— In this paper, an H∞/LPV observer to be used in an automotive suspension control application is proposed. The system considered is a road disturbance affected quarter car equipped with an industrial SOBEN damper. This observer is designed in the H∞ framework in order to minimize the effect of the unknown road disturbance on the estimated states. The damper studied in this paper is hig...
