Ride Comfort with Self-organizing Fuzzy Sliding Mode Controller for Semi-active Suspension of a Personal Car

چکیده
The semi-active suspension system can instantly change the damping coefficient depending in order to ‘stiffen’ or ‘soften’ the system. It will effectively and timely eliminate road disturbances on the car body. Thus, research on the semi-active suspension system is necessary. According to the performance test of the proposed adjustable damper, the different damping coefficients can be selected by using a stepping motor. After that, the proposed adjustable damper was installed in the 1/4 car. Besides, a self-organizing fuzzy sliding controller was used in the experiments to verify its feasibility. This study also investigates ride comfort of a 1/4 vehicle for the semi-active suspension system according to the ISO2631-1 standard. The experimental results show that the proposed controller demonstrates effective improvements in the vibration suppression of the vehicle body and ride comfort that is better than the compared fuzzy sliding mode controller design.
