Cost-Effective Skyhook Control for Semiactive Vehicle Suspension Applications

Skyhook control, which is now widely applied to vehicle suspension control, requires two sensors to measure sprung mass acceleration and relative displacement, respectively. In the practical implementation, these two measurement signals are converted into corresponding velocities; then per the skyhook control policy the velocities are employed to decide the desired damping level; finally the da...

Vehicle dynamics simulation using bond graphs

This work addresses the construction of a fourwheel, nonlinear vehicle dynamic bond graph model and its implementation in the 20sim modeling and simulation environment. Nonlinear effects arising from the coupling of vertical, longitudinal and lateral vehicle dynamics, as well as geometric nonlinearities coming from the suspension system are taken into account. Transmission and (a simplified) en...

Dynamics of an Autoparametric Pendulum-Like System with a Nonlinear Semiactive Suspension

This paper presents vibration analysis of an autoparametric pendulum-like mechanism subjected to harmonic excitation. To improve dynamics and control motions, a new suspension composed of a semiactive magnetorheological damper and a nonlinear spring is applied. The influence of essential parameters such as the nonlinear damping or stiffness on vibration, near the main parametric resonance regio...

Performance Analysis of a Semiactive Suspension System with Particle Swarm Optimization and Fuzzy Logic Control

This paper uses a quarter model of an automobile having passive and semiactive suspension systems to develop a scheme for an optimal suspension controller. Semi-active suspension is preferred over passive and active suspensions with regard to optimum performance within the constraints of weight and operational cost. A fuzzy logic controller is incorporated into the semi-active suspension system...

A Method for Efficient Simulation of Hybrid Bond Graphs

The hybrid bond graph (HBG) paradigm is a uniform, multi-domain physics-based modeling language. It incorporates controlled and autonomous mode changes as idealized switching functions that enable the reconfiguration of energy flow paths to model hybrid physical systems. Building accurate and computationally efficient simulation mechanisms fromHBGmodels is a challenging task, especially when th...
