The magnetic levitation technology has attracted blooming attention from all walks of life thanks to its superiorities such as noncontact and active control. While the intrinsic features open-loop instability strong nonlinearity, along with uncertain external disturbance make control particularly significant difficult. For speeding up convergence obtaining a better stability robustness, this article proposes an ultralocal model-free adaptive supertwisting nonsingular terminal sliding mode...

Storage ponds (storm detention ponds) are an important part of sponge city construction, and the construction process involves deep large pit excavation in a complex sensitive environment. Combined with storage pond engineering design practice process, this study, environment method has been explored, using field measurement data to test support deformation control effect summarize key, difficult points treatment measures. The results show that procedure adopted project is successful for...

This paper studies a novel form of last-mile delivery that combines optimization E-commerce and Online-to-Offline (O2O) parcels. While O2O parcels must first be picked up from shops before being delivered to the appropriate customers, are customers predetermined number depots. The goal is use same fleet vehicles provide integrated services for various merchant types. We propose branch-and-price algorithm based on set partitioning formulation, where pricing problem solved by label-setting...

Abstract The design method of “centralized acquisition, time-sharing operation and array drive” has been proposed for the integrated coordinated control black-body calibration mechanism, radiation source, focusing filter wheel mechanism thermo-threshold in an aerospace infrared remote sensor. Compared with decentralized traditional components, this uses FPGA as main chip to effectively realize function multi-component movable radiating mechanisms through pulse-width modulation drive heater...
