Full vehicle combinatory efficient damping controller: Experimental implementation uri icon

Abstract

  • © 2017 IEEE. This paper presents an experimental validation of a new control design for semi-Active suspension systems, referred to as Combinatory quasi-Optimum Damping (COD) controller. This strategy is entirely based on vehicle measurements, is multiobjective, of low computational load, and can be implemented in real time. The validation was performed on a scaled vehicle 1:5, fully instrumented and equipped with Electro-Rheological dampers. First, a frequency-domain analysis is provided from a chirp road. Then, a five bumps test is considered for time-domain validation. Compared with passive suspensions, sky-hook, and ground-hook controls, the given results prove that the COD controller allows an almost optimum distribution between comfort and road holding.
