The actuator disc model (ADM) incorporated into the k-ε turbulence of EI Kasmi is able to simulate wind farm wakes with high fidelity, which essential for layout optimization and evaluation power production in modern farms. However, effects parameter C4ε on turbulent kinetic energy (TKE) superposition areas recovery wake velocity have rarely been studied. To this end, coupled advanced ADM PHOEN...

In this paper, we present a robotic actuation system using an artificial muscle actuator based on a dielectric elastomer. A novel linear actuator called a ‘multi-stacked actuator’ is proposed that can be embedded in the phalanges of a multi-jointed robot finger. This actuator ensures a compact design of the overall system. As an example, a 2-d.o.f. robot finger is developed and its performance ...

In this paper we assume that all actuators are mobile and an event was reported to one of the actuators, and a response by one actuator is required. The goal of actuator task assignment is to select the best actuator for responding to a reported event so that communication cost for selecting, and response time for performing the task are minimized. Existing solutions, except those proposed in [...

In order to exhaustively exploit the high-level capabilities of shape memory alloys (SMAs), they must be applied in control systems applications. However, because of their hysteretic inherent, dilatory response, and nonlinear behavior, scientists are thwarted in their attempt to design controllers for actuators of such kind.  The current study aims at developing a micro-position control system ...

Elastomeric dielectric material has recently become a new alternative for actuator technology. The characteristics of dielectric elastomers placed between two electrodes to withstand large strain when electrodes are charged has attracted the attention of many researcher to study this material for actuator technology. Thus, in the past few years Danfoss Ventures A/S has established their own die...

In this paper LQG controller for TRMS without and with sensor, actuator failure is designed. Implementation of LQG controller for TRMS is done under no failure of sensor, actuator. TRMS output with LQG controller and reliable H infinity controller are compared without and with sensor, actuator failure. The objective of the proposed technique is to prove the H infinity controller is reliable ove...
