钱学森在《工程控制论》(修订版, 1980 年) 序言中, 进一步阐述了现代化、技术革命与控制论的关 系, 指出 "从科学理论的角度来看, 20 世纪上半叶的三大伟绩是相对论、量子论和控制论" [8] , 并指出 核能技术革命、计算机技术革命和航天技术革命等 "所有这些技术革命都直接与控制论连在一起" .在经典控制论中最著名的反馈控制方法是 "比例 -积分 -微分 (proportional-integral-derivative, PID) 控制".这是个具有百年历史的线性反馈控制器 [9] 在其发展过程中对控制的系统方法起过重要 作用 [10] .因为 PID 控制具有简单性、实用性和鲁棒性等突出的优点, 它在现代工程技术系统的控制 器设计中一直起主导作用.事实上, "95% 以上的工业控制问题是采用 解决的" [11] 并且迄今为 止 "仍没有其他控制方法可以与之相比" [12] .由于控制系统是自动化系统的 "大脑", 而自动化又是将 人类从繁重的体力和脑力劳动中解放出来并推动生产力发展的关键技术之一, 因此可以说 "没有 PID, 就没有现代文明".此外,...
In the applications of rail transit and electric vehicles, sensorless control interior permanent magnet synchronous motor (IPMSM) usually uses high frequency (HF) signal injection in low speed or zero speed. Rotating HF based on stationary reference frame can identify rotor position, but its accuracy is easily affected by various nonlinearities system stator resistance. this paper, causes position estimation deviation are analyzed deduced detail. It proposed that be divided into phase (HFPD)...
Combinatorial bilevel congestion pricing (CBCP), a variant of the discrete network design problem, seeks to minimize total travel time experienced by all travelers in road network, strategically selecting toll locations and determining corresponding charges. Conventional wisdom suggests that these problems are intractable since they have be formulated solved with significant number integer variables. Here, we devise scalable local algorithm for CBCP problem guarantees convergence...
Western culture attracts Chinese people’s attention unprecedentedly for China is becoming more open. For the rapid development of economy, people need to cooperate with westerners frequently. It becomes particularly important learn about western countries’ in their communication. This paper mainly focuses on traditional marriage customs and especially that United States. Though this paper, different will be demonstrated help them. based literature survey methods, attempts show US analyze...
The slow degradation of returned straw adversely affects seedling survival rate. To shorten the time lignin in maize warm temperate regions, a cellulolytic microbial strain that can secrete polymer with high enzymatic activity was isolated from humus, which helped to identify an effective expedite decomposition straw. Using molecular biology techniques primary screening and re-screening using selective media, dominant microbes humus were identified as Penicillium oxalicum (P. oxalicum)...
The goal of delivering high-quality service has spurred research 6G satellite communication networks. limited resource-allocation problem been addressed by next-generation networks, especially multilayer networks with multiple low-Earth-orbit (LEO) and non-low-Earth-orbit (NLEO) satellites. In this study, the a network consisting one NLEO LEO satellites is solved. authorized user spectrum resources are unauthorized users. resource allocation dynamic pricing problems combined, game-based...
Abstract The main content of this research is how to know the speed, location and arrival time rail train, provide information for passengers take train. Because urban transit built in underground environment, there will be some limitations selection speed measurement positioning methods trains. This based on actual situation, using hardware system single chip microcomputer as vehicle equipment, real-time measurement, prediction Provide effective data train operation, dispatching passengers’ taking.
With the development and promotion of grid technology, resource sharing has been greatly enhanced both in depth width. But along with continuous improvement for people demanding quality service provided by sharing, only using resources could have no longer meet needs people. The more stable efficient become key problems which are urgent to be solved. characteristics unstable factors, such as two-division resource, is much problem needed Aimed at itself, this paper proposed management...
