Abstract EN
In this paper, the existence condition of critical damping in 1 DOF systems with fractional damping is presented, and the relationship between critical damping coefficient and the order of the fractional derivative is derived.
It shows only when the order of fractional damping and its coefficient meet certain conditions, the system is in the critical damping case.
Then the vibration characteristics of the systems with different orders located in the critical damping set are discussed.
Based on the results, the classical skyhook damping control strategy is extended to the fractional one, where a switching control law is designed to obtain a more ideal control effect.
Based on the principle of modal coordinate transformation, a new design method of fractional skyhook damping control for full-car suspension is given.
The simulation results show that the proposed control method has a good control effect, even in some special cases, such as roads bumps.
