The use of fractional differentiation in vehicle suspension design has many interests. This paper presents a hydropneumatic suspensions design method based on fractional differentiation. Once a hydraulic structure has been chosen for the suspension, it is possible to calculate the values of all technological parameters, so that the suspension force – deflection transfer function is a band-limited fractional differentiator. The combination of the CRONE control methodology and hydropneumatic technology leads to remarkable performances of robustness. Keywords Fractional differentiation, hydropneumatic technology, CRONE control, hydropneumatic test bench.
