In the context of the benchmark problem, "Design and optimisation of restricted complexity controllers", related to an active suspension system, this paper presents the design of an initial controller based on the first and third generation Crone methodologies. The high-level parameters of the controller are then fine-tuned using a "tuned in closed-loop"(More)

The paper deals with fractional residual evaluation. Three methods to evaluate fractional residuals generated by dynamic parity space method are presented. They are based on the fractional derivative approximations: the Grunwald, the pole-zero and the Diethelm approximations. They are compared in order to select the best method in terms of precision and(More)
Identification of continuous-time non-linear systems characterised by fractional order dynamics is studied. The Riemann-Liouville definition of fractional differentiation is used. A new identification method is proposed through the extension of Hammerstein-type models by allowing their linear part to belong to the class of fractional models. Fractional(More)
