Abstract : it provides a kind of new nonlinear integrator and its mathematical model. its frequency responses is disscussed by the harmonics linearization method. its phase lag is found to be only 27. 6, all high order harmonics are very small, and it is very resistant to disturbances. by using it, an two - objective optimum control system is designed. it has very good control performances and will have good prospects in application
文摘:提出一種新型的非線性積分器,給出它的數學模型,並用諧波線性化原理討論它的頻率特性,其幅頻特性起積分作用,而相位滯后僅27 . 6 ,高次諧波分量小,抗干擾能力強.應用這種積分器設計了一個雙目標優化的二次優化系統.模擬結果表明,系統的控制性能好,具有廣泛的應用前景In the case, the subsidiary wholly owed by a corporation is a large scale state owed enterprise with glorious history rewarded for its excellent profit. but it finally failed because of its financial crisis. it is one of the important reason of the failure that the corporation could n ' t obtain the financial information in time, and could n ' t obtain the real data which misguided the corporation leaving the subsidiaries financial risk alone which resulted in the liquidation
案例中的子公司是一家大型國有企業,從集團公司財務風險控制角度分析該公司從輝煌到走向清算的歷程,本文認為子公司上報信息不及時、反饋數據不充分、溝通情況不符合實際,使集團公司預測不準確、決策相對滯后、戰略調整不到位是該財務失敗的重要原因之一。For example, the administratively monopolized access regulation that caused the upper section ( railway network operation ) and lower section ( the transportation businesses ) integrated ; the relatively closed investment mechanism that at first mainly depended on government allocation, then mainly relied on railway ' s building fund ; the price regulation that controls the right of price setting strictly and keeps a low price level for a long time ; the income distribution regulation that with its income and expense carried out in two separate ways ; finally, the regulation framework that with the roles wrongly arranged and with inadequate supervision and lagged legislation
由此可以看出,我國鐵路規制體制的計劃經濟痕跡非常明顯:在進入上,實行「上下一體」的行政性壟斷;在投資上,實行先以國家為主而後以鐵路建設基金為主的相對封閉的投資體制;在運價上,國家嚴格控制定價權,並長期以來保持低價位;在收益分配上,實行收支兩條線的清算制度;最後,在規制的組織架構方面,不僅角色錯位,而且缺乏監督,立法滯后。On the other hand, many business groups have built up the modern enterprise institution, the structures of their corporate governance are nearly perfect and their basic management works have done very well. so optimizing the financial supervision and control system and reinforcing th e inner management of the business groups become more and more important. beyond all doubt, carrying on systemic and overall theoretical research to the above - mentioned problems then announcing the results will produce the enormous social benefits and economic benefits
眾所周知,我國企業集團的組建速度大多較快而整體管理水平卻相對滯后,其間的財務監管和控制工作尤為薄弱,各成員的經營運作與集團財務管理目標經常背道而馳,作為集團公司法人治理結構的重要組成部分與集團財務體制的核心內容,財務監控體系的重要性正引起人們的普遍關注,大力推進和加強企業集團財務監控體系建設無疑具有重大的現實意義和深遠影響;另一方面,隨著我國現代企業制度的逐步到位,相當一部分治理結構較為完善和管理基礎工作比較扎實的企業集團,優化財務監控體系和進一步提升企業集團內部管理水平的呼聲正日漸高漲,毫無疑義,對上述問題進行系統全面的理論研究並將研究結果公佈於眾,必將產生巨大的社會效益和經濟效益。This thesis describes the three important methods for designing pid controller : imc - based method, frequency method and direct synthesis method. we respectively design the pid controllers for the first - order plus dead - time processes, second - order plus dead - time processes, non - minimum phase processes, integrating and unstable processes, then, performance assessment and robustness metrics are used to compare the pid controllers of the individual process
論文著重研究了pid控制器的三種重要設計方法:內模法、頻域法和直接綜合法,並從確定性性能指標和魯棒性性能指標的角度,比較這些設計方法在一階加純滯后、二階加純滯后、非最小相位、積分和不穩定過程pid控制器設計中的應用效果。In industrial the temperature system is classed large nonlinear system. with associative memory neural network as identification and fuzzy neural network as control established model reference adaptive control system, succeeded realized single dealing control. model reference adaptive control system supplied new method for other lager nonlinear system such as flux, stress and fluid system
溫度控制系統是典型的非線性大滯后控制系統,根據本文提出的聯想記憶神經網路辨識器,與模糊神經網路控制器相結合,建立模型參考自適應控制方案,成功的實現了對單腔電阻加熱爐的控制,模型參考自適應控制方案可以向其它大滯后非線性特性的過程式控制制參量(如流量、壓力、液位等)推廣。2. in chapter 2 and chapter 3, we respectively design pid controller using the three methods for stable processes, integrating and unstable processes. the pid controller performances of the individual process are compared with both deterministic performance and robustness
