PI-control in dual duct systems : a study on manual tuning and control loop interaction
Good HVAC control schemes in buildings help reduce energy use and maintain occupant comfort. PID controllers are widely used in commercial buildings to keep variables such as temperature, pressure and humidity at predefined setpoints. These controllers, when they do not include autotuners, must be …

Transient Motion Control of Passive and Semiactive Damping for Vehicle Suspensions
… a class 8 truck, using passive and semiactive dampers. The semiactive damper control policies that are examined include the previously developed policies of on-off skyhook, continuous skyhook, and on-off groundhook control, along with a newly developed method of fuzzy logic semiactive control. …

Application of Magnetorheological Dampers for Vehicle Seat Suspensions
… suspensions that employ magnetorheological (MR) dampers and skyhook control. An Isringhausen seat suspension that had been modified to replace the stock passive damper with a controllable MR damper was used to evaluate the problems and potential solutions. A seat suspension tester was built using …

Dynamic Soil-Structure Interaction In Buildings With Oil Dampers
… the seismic performance of structures with oil dampers have so far been driven primarily by the structural engineering community, with influential experimental work on the topic originating mainly from large scale shaking table testing of fixed-base prototype frames. Despite considerable …

Preview based Semi-Active Suspension Control
… level of performance. A lot of preview-based control algorithms in literature tend to require high computational effort to arrive at the optimal parameters thus making it difficult to implement in real time. Other algorithms tend to be based upon lookup tables which classify the road input …

Integration eines Fahrzeugniveausensors in ein Gummi-Metall-Lager eines Fahrwerklenkers
In zunehmendem Maße werden Kraftfahrzeuge mit Sensoren zur Erfassung des Fahrzeugniveaus, also der Lage des Fahrzeugs relativ zur Straßenoberfläche in Richtung der Fahrzeughochachse, ausgestattet. Informationen zum Fahrzeugniveau werden beispielsweise für die automatische Leuchtweitenregulierung …

Effect of Control Techniques on the Performance of Semiactive Dampers
… is used to examine the effects that various control methods have on the performance of semiactive dampers in controlling the dynamics of a single suspension (quarter car) model. The level of dynamic control of this model has a direct bearing on the ride comfort and vehicle handling, when the …
