document: Fractional differentiation in passive vibration control From a single-degree-of-freedom model used to illustrate the concept of vibration isolation , a method to transform the design for a suspension into a design for a robust controller is presented . Fractional differentiation is used to model the viscoelastic behaviour of the suspension . The use of fractional differentiation not only permits optimisation of just four suspension parameters , showing the ` compactness ' of the fractional derivative operator , but also leads to robustness of the suspension 's performance to uncertainty of the sprung mass . As an example , an engine suspension is studied
