A twin accumulator semi-active suspension system is studied theoretically using a quarter car model. A novel electromagnetic active suspension with an energy-regenerative structure is proposed to solve the suspension’s control consumption problem. Liu S., Zhou H., Luo X., Xiao J. Adaptive sliding fault tolerant control for nonlinear uncertain active suspension systems. 2007, Journal of Vibration and Control, 13(11), pp. The use of the two gear reducers makes this active suspension׳s internal friction force larger than that in normal seat suspensions and this enables the vibration energy to dissipate. The linear optimal control theory is used to derive the full state feed-forward control laws taking into account the correlation excitation with the look-ahead sensor information about the ground input. 5 No.Z J.

Active hydraulically interconnected suspension (HIS) is a promising technology to reduce vehicle body roll angle caused by different driving inputs and road conditions. [3] Figure 1. This paper proposes a novel actuator of the active HIS system. For Figure .1 Passive suspension componentIt was shown that active suspension system had a better potential to improve both the ride comfort and road holding, since the acceleration has been reduced for active CM system (19.58%) and for active ADM system (34.08%) compared to passive one [2]. For the active suspension systems shown in figure 2 can automatically vary its height to maintain the vehicle steady have been an active area of research over the last two decades to achieve a better compromise during varying driving conditions. 1.
