Application of a Combined Active Control and Fault Detection Scheme to an Active Composite Flexible Structure. [PDF]
, 2006 In this paper, the problem of increasing reliability of active control procedure is considered. Indeed, a design method of rejection perturbation in presence of potentially faults, on a flexible structure with integrated piezo-ceramics, is presented. The

Preview Estimation and Control for (Semi-) Active Suspensions
Vehicle System Dynamics, 1993 An active suspension with preview is tested for rounded pulses and a stochastic road surface, and is compared to a passive suspension. The spectacular performance improvement obtained for a step function as road surface is not achieved but the improvement is still significant. The frequency response of the active suspension is determined for comparison

Fault Tolerant Control in a Semi-Active Automotive Suspension
Revista Iberoamericana de Automática e Informática Industrial RIAI, 2016 A new active Fault Tolerant Controller (FTC) is proposed for an automotive semi-active suspension, by considering a quarter of vehicle model. The design is composed by: (1) a robust non-linear controller used to isolate vibrations into the vehicle caused

A Hybrid Control Policy for Semi-Active Vehicle Suspensions
Shock and Vibration, 2003 Various control policies, such as skyhook and groundhook control, have often been considered for semi-active vehicle suspensions. Past studies have shown the performance limitations of these policies, as well as others that have been considered for ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Active, semi-active and hybrid control of structures
Bulletin of the New Zealand Society for Earthquake Engineering, 2000 In recent years, considerable attention has been paid to research and development of passive and active structural control devices, with particular emphasis on alleviation of wind and seismic response of buildings and bridges. In both areas, serious efforts have been undertaken to develop the structural control concept into a workable technology, and ...
