Adaptive fuzzy integral sliding mode velocity control for the cutting system of a trench cutter

Qi-yan Tian, Jian-hua Wei, Jin-hui Fang, Kai Guo,jhfang@zju.edu.cn

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 1,   Pages 55-66 doi: 10.1631/FITEE.15a0160

Abstract: This paper presents a velocity controller for the of a trench cutter (TC). The cutting velocity of a is affected by the unknown load characteristics of rock and soil. In addition, geological conditions vary with time. Due to the complex load characteristics of rock and soil, the cutting load torque of a cutter is related to the geological conditions and the feeding velocity of the cutter. Moreover, a cutter’s dynamic model is subjected to uncertainties with unknown effects on its function. In this study, to deal with the particular characteristics of a , a novel (AFISMC) is designed for controlling cutting velocity. The model combines the robust characteristics of an integral sliding mode controller with the adaptive adjusting characteristics of an adaptive fuzzy controller. The AFISMC ler is synthesized using the backstepping technique. The stability of the whole system including the fuzzy inference system, integral sliding mode controller, and the is proven using the Lyapunov theory. Experiments have been conducted on a TC test bench with the AFISMC under different operating conditions. The experimental results demonstrate that the proposed AFISMC ler gives a superior and robust velocity tracking performance.

Platinum on nitrogen doped graphene and tungsten carbide supports for ammonia electro-oxidation reaction

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 6,   Pages 930-938 doi: 10.1007/s11705-021-2130-2

Abstract: Ammonia electrooxidation reaction involving multistep electron-proton transfer is a significant reaction for fuel cells, hydrogen production and understanding nitrogen cycle. Platinum has been established as the best electrocatalyst for ammonia oxidation in aqueous alkaline media. In this study, Pt/nitrogen-doped graphene (NDG) and Pt/tungsten monocarbide (WC)/NDG are synthesized by a wet chemistry method and their ammonia oxidation activities are compared to commercial Pt/C. Pt/NDG exhibits a specific activity of 0.472 mA∙cm–2, which is 44% higher than commercial Pt/C, thus establishing NDG as a more effective support than carbon black. Moreover, it is demonstrated that WC as a support also impacts the activity with further 30% increase in comparison to NDG. Surface modification with Ir resulted in the best electrocatalytic activity with Pt-Ir/WC/NDG having almost thrice the current density of commercial Pt/C. This work adds insights regarding the role of NDG and WC as efficient supports along with significant impact of Ir surface modification.
