“…To control the developed problem they proposed Takagi-Sugeno (T-S) fuzzy approach to describe the original nonlinear system using a nonlinearity sector. A spatial vehicle model is designed by Demić et al (2006) which worked without filtered feedback of the control system to improve active suspension system. One significant aspect of their research was using stochastic parameters optimization of active suspension system.…”

In this research a new electronic based mechanism for vehicle suspension system is designd. The aims are to improve passengers' safety and comfort. The proposed system is developed for proactive rapid reaction of suspension system which can readjust the height of chassis while confronting with wrong conditions of driving such as unflatted road, rainy or snowy road profile. The results show that the proposed mechanism can successfully increase the stability of the car by readjusting the height of the the chassis and center of the gravity of vehicle while turning.

“…Motor vehicles have complex dynamic characteristics, which are displayed by the appearance of spatial movements, variation of characteristics during operation, a number of disturbing influences, the appearance of clearances, friction, hysteresis, etc. [1,2,[13][14][15][16][17][18][19][20][21]. The above mentioned dynamic phenomena, especially vibrations, lead to the fatigue of passengers and driver, reduce service life of the vehicle and its systems, etc.…”

Dynamic simulation, based on modelling, has a significant role during to the process of vehicle development. It is especially important in the first design stages, when relevant parameters are to be defined. Shock absorber, as an executive part of a semi-active suspension system, is exposed to thermal loads which can lead to its damage and degradation of characteristics. Therefore, this paper attempts to analyse a conversion of mechanical work into heat energy by use of a method of dynamic simulation. The issue of heat dissipation from the shock absorber has not been taken into consideration.

“…The focus of this paper is a mathematical model of the active damping force and its optimization. The optimization process for design parameters is done by non-linear programming using the stochastic parametric optimization method, Pajaziti [10] and Demic et al [15]. Optimal design parameters are obtained when the objective function reaches minimal values.…”

This paper introduces a design and optimization procedure for active and semi-active non-linear suspension systems regarding terrain vehicles. The objective of this approach is the ability to quickly analyze vehicles' suspension performances resulting from passive, active, or semi-active systems. The vehicle is represented by a mathematical model regarding a quarter of it, and equations for motion are derived and solved by using MATLAB/Simulink. In order to verify the reliability of the derived computer program, a comparison is made with one of the comprehensive commercial software packages. The decision parameters of the active damping device are optimized by using the Hooke-Jeeves method, which is based on non-linear programming. The usefulness of the treated active and semi-active systems on a concrete terrain vehicle is presented and compared with the presented passive systems by analyzing the vehicle's body acceleration, velocity, displacement, and vertical tire force, namely those aspects that directly influence driving comfort and safety.
