This paper presents the control of an electropneumatic system used for moving steering mechanism. aeronautic application needs a high-precision position and high bandwidth. The structure experimental setup benchmark on which controllers are evaluated have been designed in order to precisely check use such actuator aeronautics. Two kinds designed: linear one based gain scheduling feedback, two sliding mode ensuring finite-time convergence, accuracy robustness. Experimental results display...
This paper presents the synthesis and experimental implementation of robust higher order sliding mode controllers for an electropneumatic actuator. These are based on a recent approach designed in monovariable (position control) multivariable pressure contexts. The controllers' robustness is analysed with respect to parameters uncertainties load disturbances.
This paper presents a synthesis of nonlinear controller to an electropneumatic system. Nonlinear backstepping control and sliding mode laws are applied the system under consideration. First, model is presented. It transformed be affine coordinate transformation then made possible by implementation controller. Two kinds developed track desired position pressure.

Hybrid bonding pitch scaling is critical to continue support higher chip bandwidth at reduced area and power overhead for chip-to-chip signaling. This paper discusses the scalability of hybrid down 0.36 μm (or over 7.7M connections/mm2) on Intel backend process. We designed manufactured an electrically testable test with 0.64, 0.48 pitch, utilizing a dual damascene via-trench fabrication The pre-bond metal-dielectric surface polish process was optimized achieve required topography roughness...

Different kinds model, namely a affine linearized tangent model reduced synthesize different laws. For new mathematical modelling servo-distributor flow stage described.
Starting from an examination of vital energy in two essays by Virginia Woolf—‘The Death the Moth’ and ‘Evening over Sussex: Reflections a Motor Car’, both initially published posthumous collection The Moth Other Essays (1942)—this article establishes that ‘life’ is conceived Woolf as process circulation exchange, extending beyond diegetic level to embrace relationship between reader narrative voice. What seeks set up ‘The Moth’, Sussex’ other short writings fostering sense intimacy with...

Abstract This paper deals with the robust control problem of a pneumatic actuator subject to parameter uncertainties and load disturbances. The strategies are based on second‐ third‐order sliding mode approaches. These controllers require measurements acceleration for feedback. However, accelerometer is seldom used in practical drive systems, because complexity they add overall process as mounted displacement. For this, differentiator via estimate acceleration. A comparative study between...

Generally, it supposed that these servodistributors are equivalent one five-way servodistributor when they controlled with inputs opposite signs. In case, a monovariable control law can be established. However, the servodistributors, possible different trajectories. For example, seems useful position and pressure without...
Today, medical simulators are increasingly gaining appeal in clinical settings. In obstetrics childbirth provide a training and research tool for comparing various techniques that use obstetrical instruments or validating new methods. Especially the case of difficult deliveries, instruments-such as forceps, spatulas, vacuum extractors-has become essential. However, such increase risk injury to both mother fetus. Only experience acquired delivery room enables health professionals reduce this...
