Buffering Capacity of Non-convex Granular Materials Based on Discrete Element Method

Complex systems composed of non-sphericalparticles are widely present in nature or industry,and their low flow and highinterlocking properties under external impact loads cause the energy of thesystem to be effectively attenuated,thereby achieving buffering.In thispaper,the discrete element method was used to numerically analyze thecushioning properties of non-convex granular materials,such as E-,U-anddolos-shaped(twisted H-shaped),under impact load.The calculation results showthat the non-convex...

Entropy-based Performance Assessment of Batch Process with non-Gaussian Disturbances under Data-Driv

This paper proposed an entropy-based performanceassessment method for batch processes with non-Gaussian disturbances.Real batchprocesses have some intrinsic non-linear characteristics,which makes systemoutput be non-Gaussian even though disturbances obey Gaussian distribution.Inthis case,minimum variance control(MVC)based performance assessment method isnot applieable to batch processes.Consequently,in order to reject non-Gaussiandisturbance,entropy is adopted to provide a unified controller perf...
