Adaptive Nonlinear Control in Active Suspensions 1
We study the sensitivity of a recently developed nonlinear control scheme with respect to variations in the parameters of the active suspension. Based on comparative simulation results, we conclude that the parameters of the hydraulic actuator dynamics are the ones to which closed-loop system performance is most sensitive. In fact, it is enough to estimate only one parameter in order to guarant...
متن کاملStability of active suspensions.
We study theoretically the stability of "active suspensions," modeled here as a Stokesian fluid in which are suspended motile particles. The basis of our study is a kinetic model recently posed by Saintillan and Shelley [D. Saintillan and M. J. Shelley, Phys. Rev. Lett. 100, 178103 (2008); D. Saintillan and M. J. Shelley, Phys. Fluids 20, 123304 (2008)] where the motile particles are either "pu...
متن کاملTheory of active suspensions
Active suspensions, of which a bath of swimming microorganisms is a paradigmatic example, denote large collections of individual particles or macromolecules capable of converting fuel into mechanical work and microstructural stresses. Such systems, which have excited much research in the last decade, exhibit complex dynamical behaviors such as large-scale correlated motions and pattern formatio...
متن کاملWireless sensor networks for active vibration control in automobile structures
Wireless sensor networks (WSNs) are nowadays widely used in monitoring and tracking applications. This paper presents the feasibility of using WSNs in active vibration control strategies. The method employed here involves active-structural acoustic control using piezoelectric sensors distributed on a car structure. This system aims at being merged with a WSN whose head node collects data and pr...
متن کاملRobust Control of Quarter-car Semi-active Suspensions
This paper deals with single-wheel suspension car model. The benefits of controlled semi-active suspensions compared to passive ones are here emphasized. The contribution relies on robust analysis of a controller which improves comfort and road holding of the car under industrial specifications. Simulations on an exact nonlinear model of the suspension are performed for control validation.
