Paper Abstract

Skyhook control is an effective control strategy for suppressing vehicle vibration. It is typically classified as on-off skyhook control and continuous skyhook control. In this study, a fuzzy skyhook control is proposed. It combines the fuzzy logic theory with the skyhook principle to improve control performance. In order to compare performance of each control strategy, an experimental study is prepared utilizing a quarter car model of high-mobility multi-purpose wheeled vehicle (HMMWV) with a controllable magneto-rheological fluid (MRF) damper. The experimental results under rough road excitation demonstrate that the fuzzy skyhook control offers more robust suspension performance over the continuous skyhook control while still out performing the on-off skyhook control. The system model-independent fuzzy skyhook control is simpler and provides some robust advantages for real application as compared to the system model-dependent continuous skyhook control.
