This paper deals with the high-precision positioning control of a dual-stage feed drive. The design system is based on equivalent input-disturbance (EID) approach to improve disturbance rejection performance. An analysis EID reveals mechanism rejection. procedure illustrated by numerical example. Simulation results show that not only rejects disturbances, but also suppresses uncertainties and nonlinearities in plant. Design simulation for example are employed compare our method observer...
The modification of the material surface by second-phase particles enables electron interaction on Fermi level or energy band between different materials, which can achieve improvement gas-sensing properties. Herein, a novel composite PbS quantum-dots-modified MoS2 (MoS2/PbS) is synthesized combination hydrothermal method with chemical precipitation and fabricated into gas sensor to investigate its enhanced properties caused quantum dots at room temperature. It found that responsivity...
The unique properties of MoS2 nanosheets make them a promising candidate for high-performance room temperature gas detection. Herein, few-layer (FLMN) prepared via mechanical exfoliation are coated on substrate with interdigital electrodes room-temperature NO2 Interestingly, compared other sensors based MoS2, FLMN exhibit high responsivity detection, and is easily desorbed from the sensor surface an ultrafast recovery behavior, times around 2 s. related to fact that adsorbed can affect...
As a class of underactuated systems, cooperative dual rotary crane systems (DRCSs) are widely used to complete the task large payload transportation in complex environments, since working capacity single cranes is quite limited. However, control issues DRCS fail receive enough attention at present. Compared with cranes, DRCSs contain more state variables, geometric constraints, and coupling relationships. Therefore, kinematic dynamic characteristics make controller design/stability analysis...
For robot manipulators subject to unmeasurable/uncertain plant parameters, this article designs a <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">new</i> adaptive motion controller, which ensures positioning errors converge zero and provides accurate gravity compensation. Meanwhile, specific constraints are also satisfied during the entire control process. Additionally, proposed controller is further extended address output feedback without...
Four products were obtained from sodium dodecylbenzene sulfonate (SDBS) and formaldehyde (40% solution) using a simple reaction. The characterized by TGA, IR, UV MS to confirm the major chemicals in each sample. new could reduce interfacial tension between oil water experimental temperature range further compared SDBS. emulsion ability was also enhanced SDBS-1 SDBS-4. oil-displacement efficiencies of SDBS-4 obviously higher than that SDBS, efficiency SDBS-2 best, with an 25%. results all...
This paper concerns a swing-up control problem for three-link gymnastic planar robot in vertical plane with its first joint being passive (unactuated) and the rest active (actuated). The objectives of this are to: (1) design controller under which can be brought into any arbitrarily small neighborhood upright equilibrium point, where all three links remain their positions; (2) attain global analysis motion controller. To tailor energy-based approach to achieve aforementioned objectives,...
This brief concerns the energy-based swing-up control for a remotely driven acrobot (RDA) which is 2-link planar robot with first link being underactuated and second by an actuator mounted at fixed base through belt. An controller designed via Lyapunov stability theory. A global motion analysis of RDA under provided focusing on behavior closed-loop solution equilibrium points. The conditions parameters achieving successful are given. Furthermore, experimental setup described results given to...
Abstract Gynaephora menyuanensis Yan & Zhou is one of the most devastating pests that harm ecosystem alpine meadows and hinder advancement animal husbandry. However, current knowledge morphology different developmental stages within G. reveals an information deficit needs to be addressed. This study first report life history, sexual dimorphism, eggs, mature larvae, pupae, adult antennal sensilla types menyuanensis. used a K-means clustering method, based on head width, body length,...
In this paper, we introduce a stability analysis approach for systems with two-degree-of-freedom control by converting the linear continuous time-varying system into periodic one and applying criterion of continuous-time (LCP) systems. We illustrate swing-up task rotary inverted pendulum system. It includes three steps. First, design orbit adding (virtual) swing-down phase. Second, controller which alternates between controllers in piecewise manner. phase, comprises both feedforward feedback...
