In large-scale air conditioning water systems, variable flow (VWF) control strategies are frequently utilized to conserve energy. This paper presents a differential pressure (DP) set-point strategy for VWF systems based on the pipeline characteristic curve. bifurcates most unfavorable loop into two segments: equivalent main pipe (EMP) and terminal branch (MUTBP). Initially, impedance of EMP is ...

abstract- a real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. the image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. the image frames were processed by labview® and matlab®. the developed algorithm, based on weed coverage ratio and seg...

An analysis of on-line autonomous robust tracking controller based on variable structure control is presented for an aerospace launch vehicle. Decentralized sliding-mode controller is designed to achieve the decoupled asymptotic tracking of guidance commands upon plant uncertainties and external disturbances. Development and application of the controller for an aerospace launch vehicle during a...
