This paper proposes a new switching adaptive fuzzy controller and applies it to vibration control of vehicle seat suspension equipped with semi-active magnetorheological (MR) damper. The proposed system consists three functioned filters: (1) Filter 1: model interval type 2 compensate disturbances; (2) 2: ‘switching term’ evaluate the magnitude disturbance; (3) 3: group adaptation laws enhance r...

Magneto-rheological (MR) elastomers contain micro-/nano-sized ferromagnetic particles dispersed in a soft elastomer matrix, and their rheological properties (storage and loss moduli) exhibit a significant dependence on the application of a magnetic field (namely MR effect). Conversely, it is reported in this work that this multiphysics coupling is associated with an inverse effect (i.e. the dep...

The vibration control of a seat suspension system with magnetorheological (MR) damper is investigated in this study. Firstly, a dynamical model of the seat suspension system with parameter uncertainties (such as mass, stiffness, damping) and actuator saturation is established. Secondly, based on Lyapunov functional theory and considering constraint conditions for damping force, the semi-active ...

This paper presents a comparative study between different nonlinear damper models, developed for semi-active Electro-Rheological damper. The first model is by extending the hysteresis to obtain dynamic characteristic of To improve accuracy capturing damper’s behavior, Bouc-Wen using parameter-varying functions control input and state. One key points in proposed models describe dynamics controll...
