Analyzing the physics structure of vorticity, divergence, vertical velocity, frontogenesis " function, apparent heat source and apparent moist sink etc. indicated the physics fields are favorable for the occurance of the heavy rain over changjiang - huaihe river basin where the physics values are well according to the heavy rainstorm positions ; the low level jet is closely subject to the moisture and the coupled system of the low and the upper level jetstreams induced the strongly " ascending motion ; the intensity of the frontogenesis varies with the development of the rainfall system and reacts the rainfall intensity
主要分析了這次過程中的多種物理量，包括渦度、散度、垂直速度、鋒生函數、視熱源、視水汽匯等，對這一暴雨過程有了比較系統的認識。結果表明：在江淮流域存在著有利於發生暴雨的物理量場配置，渦度、散度、垂直速度等物理量，與暴雨的落區都很吻合的；低空急流的產生不僅有利於水汽的輸送，而且高低空急流的耦合造成了有利於強上升運動的配置；鋒生強度隨著降水系統的發展變化，並影響降水強度。 -
Motion control is a comprehensive subject. modern ac drive is a important embranchment in the field of motion control. however, it is difficult to rea1ize high - performance ac drive systems because induction motors are a kind of strongly - coupled nonlinear system with many variables and the torque is not easy to control. with vector control technology decoupling and torque control of ac motor are solved. the basic idea of vector control is that three - phase system is equiva1ent to two - phase system by coordinate transformation and it realizes the decoupling between field current and torque current of the stator in order to control the flux and current respectively, thus induction motor can be considered dc motor and high performance is achieved easily. with the progress of electric and electronic technology and the development of computer, high - integrated special modules and high - precision digital signal processor ( dsp ) are applied to ac drive so that vector control has been developed rapidly
但是高性能的交流調速系統實現很困難，這是因為交流電機是多變量、強耦合的非線性系統，不易實現高性能轉矩控制。矢量控制技術則解決了交流電機解耦與轉矩控制問題，其基本思路? ?應用坐標變換將三相等效為二相，實現定子勵磁電流分量與轉矩電流分量之間的解耦，達到對交流電機磁鏈與電流分別控制的目的，交流電機等效為直流電機實現高性能調速。隨著電力電子技術的進步，計算機技術飛躍發展，高度集成的專用模塊和高精度的數字信號處理器應用於交流傳動系統中，促進矢量控制迅猛發展，日趨成熟。 -
At present, variable air volume ( vav ) air - conditioning system is the main steam of the whole air conditioning system in china and abroad because of its large energy conservatioa however, since vav system is multivariable, strongly coupled, nonlinear and time variant, its design, performance and management are more difficult than constant air volume ( cav ) system, and stable control of the entire vav system is focused in particular in china study on the stability, the key condition of the vav operation, the paper divide the vav system into ahu part and terminal part based on the coordination control strategy
目前，變風量（ variableairvolume ， vav ）空調系統以其巨大的節能潛力逐漸成為國內外空調系統的主流。但是，變風量（ vav ）空調系統具有多變量、強耦合、非線性、時變的特點，因此它的設計、運行和管理都比定風量（ constantairvolume ， cav ）系統難度大。這也是限制vav系統更廣泛應用的一個重要原因。 -
The ml converter is a multi - input and multi - output, strongly coupled nonlinearly system, its control elements ( duty cycles ) and the controlled elements ( output voltage and flying capacitor voltages ) of the ml converter are strongly coupled, so the system should be decoupled to multiple single - input and single - output sub - systems such that each output can be controlled independently
多電平變換器的控制量（各開關管占空比）和被控量（輸出電壓及各飛跨電容電壓）之間存在耦合關系，它是一個多輸入多輸出、強耦合的非線性系統，因此需要將其解耦成多個單輸入單輸出系統，以對被控量進行獨立的閉環控制。 -
