Self-tuning fuzzy logic control of quarter car and bridge interaction model

In this study, active suspension control of the interaction between bridge can be modeled according to Euler-Bernoulli beam theory, and quarter car model with three degrees freedom is studied. The system consists a spring, damper, linear actuator. designed using classical PID self-tuning fuzzy (STFPID) reduce vehicle body's disruptive effects. To determine performance controllers, two different road profiles oscillations caused by flexibility were considered as effect vehicle. When simulation results examined in terms passenger seat displacement acceleration, proposed STFPID method significantly increased holding ride comfort.
