Abstract This paper presents a compliant variable admittance adaptive fixed-time sliding mode control (SMC) algorithm for trajectory tracking of robotic manipulators. Specifically, and an SMC are combined to construct double-loop structure. In the outer loop, is developed adjust parameters during collision minimize time, which gives robot compliance property reduce rigid influence. Then, by employing Lyapunov theory stability theory, new nonsingular manifold proposed presented in inner loop....
Abstract This paper addresses the control problem of Takagi–Sugeno fuzzy semi‐Markov jump systems (TFSMJSs) under finite‐time analysis and synthesis framework. Due to commonly used networked communication structure, semi‐Markovian jumping modes premise variables cannot always perfectly match for system controller among whole operation. More precisely, both asynchronous phenomena in membership mode are taken into account, then, mode‐dependent controllers developed with these features. By...
A series of [FePt(4min)/Fe(tFe)]10 multilayers were prepared by RF magnetron sputtering and post annealing. The structures, morphology, composition, magnetic properties measured XRD, SEM, EDX VSM. X-ray diffraction showed that lattice constants FePt phase changed with Fe layer thickness annealing temperature. Both a c are smaller than the standard values decreases as deposition time increases. grain sizes samples annealed at 500°C increase slightly, while those 600°C sharply decreases....
In the context of economic globalization and high-tech development, industrial integration is a new way development.It promotes realization sports tourism (ST) industries provides policy support for two major industries.In order to promote coupling between ST industry in Hunan Province, this paper analyzes development status finds driving force combination most suitable path model Province.Secondly, based on investment output data five stages Province from 2010 2020, using direct consumption...
This paper develops a combined active and passive adaptive variable admittance compliant control algorithm for space robotic manipulators. In fact, the assembly task robots requires compliance precision while ensuring avoidance of any occurrences rigid collision throughout process. Therefore, we design new structure with following three parts to meet these acquirements. Firstly, develop an facilitate robot rapid movement, enabling it achieve higher speeds maintaining compliance. Then,...
Evaluation index system of reverse logistics partners is designed from four aspects: cost, environment performance and basic factors an enterprise, combined with features automobile manufacturing enterprises. Meanwhile, weight indexes derived integrated method, TOPSIS method adopted for evaluation. An example given to show the feasibility in selection
Nano-granulation process of Cu/Co system is investigated on the route bulk mechanical alloying. Using alloying, super-satu rated solid solution Cu-20mol%Co has been prepared. Through further h eat treatment, Co nano-precipitated from super-saturated solut ion in copper matrix, resulting appearance giant magneto-resis tance. In present study, nano-precipitation and Co-particu late size by XRD, VSM TEM. The relationship between magneto-resistance ratio investi gated. This relation depends both...
The non-oriented Fe-6.5wt.%Si alloy as-cast strip prepared by the top side-pouring twin-roll casting (TSTRC) process, solidification structure of is uniform and fine equiaxed grain structure. This paper studied mechanical properties, fracture morphology, ordered phase types strips at different temperatures. results show that yield tensile strength decreased gradually with increase temperature, elongation after increased gradually. temperature rise prevented formation cleavage cracks, an...
Aiming at the problem that risk assessment of mechanical product design stage change state man, machine and environment were ignored in use stage, a safety early warning method oriented to is proposed. Firstly, concept defined. Secondly, it provides general process warning, including determination monitoring elements, value calculation model, level, etc. Finally, an industrial robot system taken as example carry out experiment. The experimental results show can take changes people, machines...
