We consider the characteristics of automatic warehousing systems with irregular positions, in order to improve the optimization control objectives of the overall working efficiency and space utilization, this paper studies the irregular storage optimization distribution strategy, presents the mathematical model to optimize the irregular storage area and each storage location, and then two-level...

The proposition that the mental lexicon is a ‘dual route’ system, advanced by Pinker and others to account for regular and irregular morphology, overlooks the important fact that morphological regularity correlates inversely with phonological regularity --‘regular’ past-tense beeped being phonologically irregular (exceptional syllable), while ‘irregular’ past-tense kept is phonologically just r...

This paper discusses the optimal H∞ control synthesis via discrete Riccati equations for hard disk drives (HDDs) with an irregular sampling rate. A HDD servo system with an irregular sampling rate, caused by missing position error signal sampling data, is modeled as a linear periodically timevarying (LPTV) system. An optimal H∞ track-following control algorithm for HDD servo systems with irregu...
