چکیده
Passenger comfort and vehicle stability are key aspects that must be guaranteed on ground vehicles, semi-active suspensions have offered an outstanding solution to meet these opposite objectives. This contribution describes a novel autoregressive with exogenous input (ARX) model-based predictive control strategy handled by driver block applied suspension improve passenger road holding when compared against passive system another more complex designs reported in the literature. The ARX model employs reduce computational load of closed-loop suspension. In addition, controller’s formulation case study consider actuator’s physical constraints achieve realistic results. case-study includes one-quarter two degrees-of-freedom, numerical data comes from real magnetorheological damper characterization. results, frequency-domain time-domain, measured based specific performance criteria. A substantial improvement is quantified discussed. For broader perspective findings, results work. research effort could basis further studies robust solutions such as adaptive/optimal controllers vehicle’s stability.
