解釋
慢變量-
Abstract : the theory of variable structure control of sing ular nonlinear control systems was considered based on the singular nonlinear systems itself by employing the method of geography, and gives the sufficient condition of existence of variable structure control and approximation theory of real sliding mode. it is shown that sliding condition only guarantee the slow - varying state of real sliding mode approach that of ideal sliding mode but not guarantee the fast - varying state of real sliding mode approach that of ideal sliding mode. the method applied for studying normal nonlinear system can not be used directely to singular nonlinear system
文摘:利用幾何方法，從廣義非線性系統本身出發，研究了廣義非線性控制系統的變結構控制理論，給出了系統存在變結構控制的充分條件及實際滑動模的近似定理.從所得結論可知，滑動條件僅能保證實際滑動模的慢變狀態趨近於理想滑動模的慢變狀態，而不能保證實際滑動模的快變狀態趨近於理想滑動模的快變狀態，研究正常非線性系統的方法已不能簡單地被利用到廣義非線性系統 -
But there are some problems in normal turbocharger, for example, the low speed engine torque is deficiency, the engine ca n ' t works with full capacity when in part load, the transient response remains slow, to improve all the above, the variable geometry turbocharger ( vgt ) comes out to be an effective way
由於常規渦輪增壓存在低速轉矩不足、部分負荷經濟性差和瞬態響應遲緩的問題，而採用可變幾何截面渦輪增壓是解決這些問題比較有效的方案。本文以vgt60增壓器和yn4100qbz柴油機為研究對象，開發了可變幾何截面增壓器電控系統硬體。 -
This article introduces a variable of institutions into slow - swan model and assumes physical investment and technological progress are the function of institutions
將制度作為一個變量引入索洛模型，可以構造一個包含制度的、技術內生的增長模型。 -
The engines would have variable nozzles, which would be fully opened on take - off and landing, so that the exhaust would be slow and relatively quiet, and narrowed when the aircraft was cruising, providing the necessary speed
引擎將配有大小可以調節的尾噴管：起飛和降落時會全部打開，這樣噴氣速度會下降、噪音也會更小；而巡航飛行過程中，尾噴管將變小以保證必要的飛行速度。
