The analysis of recent and classical on-off controllers for semi-active suspensions are presented. The research is supported by a realistic platform consisting of an industrial ECU based on a controller area network (CAN) interfacing a real time simulation system. Two experimental models, quarter of a vehicle and semi-active (SA) damper allow to represent the realistic behavior of the vehicle and electrical/network parts. The proposed non-linear model of the SA damper permits its inclusion in the real time simulator without computing issues and valid damper characteristics. A qualitative and quantitative analysis of each controller is proposed in this paper oriented to real time implantation. The requirement for the sampling time for the analyzed controllers is discussed.
