Improved Road Handling Performance with Fuzzy Logic Controller for a Coach Bus

OpenAlex İngilizce

The present study investigates the effects of semi-active suspension systems controlled by skyhook, balance and fuzzy logic controllers on ride quality and road handling performances of a coach bus. The suspension dynamics are constructed as 7 DOF full vehicle models in MATLAB using Simulink toolbox. To compare the performances of different models, some virtual tests are carried out at a constant vehicle speed on a step input in Simulink and their tire deflections, suspension travels and body motions such as bouncing and pitching oscillations are evaluated. The results show that the fuzzy logic controller (FLC) developed in this study improves road handling performance of a coach bus while maintaining its comfort level.
