“…Therefore, a continuous feedback control method based on the synchronization properties proposed by Pyragas [27] and Kapitaniak [28] is used herein to convert chaos into periodic motion using feedback combined with the application of a periodic external force of a special form. This technique has also been extensively used in various physical chaotic systems [29,30]. Chang [29] adopted the synchronization and the continuous control approach to control a chaotic automotive wiper system.…”

“…Chang [29] adopted the synchronization and the continuous control approach to control a chaotic automotive wiper system. Chang [30] also applied this control scheme to convert chaotic motion to a stable equilibrium in a steer-by-wire vehicle dynamic system. This study demonstrates the feasibility and efficiency of the proposed control chaos procedure in enhancing the performance of an electromagnetic system, as confirmed by simulations.…”

This study confirms the chaotic motion of an electromagnetic dynamic system and then elucidates the application of synchronization to an electromagnetic system to control the chaos. A bifurcation diagram reveals rich non-linear behaviour over a range of parameter values. Next, the Lyapunov exponent procedure is employed to show the occurrence of chaotic motion and to verify the results of numerical simulation. Finally, a continuous feedback control approach based on the synchronization characteristics is developed to control a chaotic electromagnetic system. Simulation results demonstrate the feasibility of the proposed method.

“…It uses an electric controller in place of a direct mechanical linkage or steering column to steer the wheel [8]. The obvious difference between this design and the conventional steering design is the removal of the steering shaft and column, which means there is no physical connection between the steering wheel and the rack and pinion setup [9,10]. The advantages of having SBW installed are that it allows improved handling performance at high speed [10], the steering ratio and effort to turn the steering can be adjusted [11], and it also provides freedom in terms of packaging, as a more space-efficient steering design can be introduced [11,12].…”

This paper presents a ride comfort analysis for a vehicle equipped with a novel steering system called the Semi-Active Steering system (SAS). Current vehicle steering systems, especially in cars which are equipped with a rack and pinion steering system, cause discomfort to the driver whenever the vehicle is driven on an uneven surface or over a pot hole. The driver may feel the vibration on the steering wheel due to the mechanical linkage of the rack and pinion steering system. The unique design of SAS which omits the solid linkage and replaces it with a low stiffness resilient shaft has made it possible to reduce the discomfort felt by the driver. In this research, two vehicle models were built in vehicle simulation software; one with a normal rack and pinion steering system and the other with the SAS system. Both vehicles were simulated on a four-post suspension test rig. Vibrations and steering wheel feel were observed and compared between the two models. The results show that the vehicle with the SAS system managed to improve the comfort by reducing the amount of vibration at the steering wheel. The findings may be useful for car manufacturers to improve the ride and comfort of the vehicle.
