A suspension system is one of the integral parts a hyperloop capsule train, which used to isolate car-body from bogie vibration provide safer and comfortable service. semi-active best candidates for its advantageous features. The performance relies greatly on control strategy applied. In this article, Skyhook (SH) mixed Skyhook-Acceleration Driven Damper (SH-ADD) controlling algorithms are adop...

Negative consequences of car use along with deficiencies for investment in environmental friendly modes, have driven authorities to search for soft measure in order to encourage people for modal shift. The main objective of this study is to propose a model which describes car use behavior on parents’ work trips and how this relates to mode choice regarding their children’s school trips. A quest...

A novel fuzzy-logic-based control for vehicle-active suspension is suggested. The vehicle vibration and disturbance are reduced considerably with a fuzzy logic controller, to enhance comfort in riding faced with uncertain road terrains. A quarter-car active suspension system is controlled to reduce the vertical acceleration to a level of, that of, a hypothetical reference model. A new look-up t...

In this paper the vibration suppression problem relative to the vertical motion of road vehicles is investigated. In particular, the goal of the research is to design control laws for active suspension systems of road vehicles in order to reduce unwanted vibrations induced by a rough road profile. The road vehicle has been represented with a quarter-car model whereas the suspension system has b...

This paper proposes a novel method for designing robust nonlinear multivariable predictive control for nonlinear active suspension systems via the Takagi-Sugeno fuzzy approach. The controller design is converted to a convex optimization problem with linear matrix inequality constraints. The stability of the control system is achieved by the use of terminal constraints, in particular the Constra...

The paper presents the virtual model of the active suspension system used for improving the dynamic behavior of a motor vehicle. The study is focused on the design of the control system, the purpose being to minimize the effect of the road disturbances (which are considered as perturbations for the control system). The analysis is performed for a quarter-car model, which corresponds to the susp...

This paper presents a simulation-based study of the performance achievable by a continuously variable electro-hydraulic semi-active suspension system. By applying state-of-the-art dynamic optimization techniques, a direct optimal controller is developed for a nonlinear quarter car model that includes an identified semi-physical damper model. The direct optimal control approach offers an intuiti...
