“…In Savaresi and Spelta [2007], it has been shown that the skyhook logic approaches the filtering limit of a semi-active suspension; indeed, most of the literature is based on variations of this control logic which was first proposed in Karnopp [1995]. Variations of the skyhook logic can be found in Poussot-Vassal et al [2006], Song [2009], Yao et al [2002], Savaresi and Spelta [2008], Li et al [2009], Nie et al [2017]. The other aspect is the literature regarding the control of the damping force in a magnetorheological damper; in Sims et al [1997Sims et al [ , 2000, the authors developed a scheme to track a reference damping force in a MR damper by controlling the input current, regardless of the application (e.g., automotive).…”
