In this works, a combination of skyhook and groundhook control based magneto rheological lookup table technique called hybrid control for a quarter car is developed. Using the vertical acceleration measured data, the absolute velocity of the vehicle (sprung mass) and its relative velocity were estimated using bandpass filter. The effects of the mass distribution of a vehicle supported by a spring and load asymmetry due to changes in speed and displacement at the damping point are analyzed. The characteristics of the damper produced by the hybrid-lookup table control and the system's response to the road profile are evaluated. Simulation of the semiactive suspension design was integrated with the hybrid controller (integration of the sky-groundhook controls) based lookup table, then compared to the skyhook controller and hybrid conventional. The simulation indicates that the proposed Hybrid control lookup table provides better vibration isolation capability than other methods.
