unstable loop
解釋
不穩定環-
In the part of the experimental designs, a experimental configuration of an unstable cavity by use of two bbo crystals compensating the walkoff effect and pumped by reflection is presented, and two set of controlling systems designs of open and closed loop are also presented ; we realized closed loop controlling system of bbo optical parametric oscillator tuning system, by using american general scanning inc. ' s controller to control bbo crystal ' s rotation, and scaled the output wavelength with charge coupled device
在實驗設計上給出了利用兩塊bbo晶體補償走離效應返回式泵浦非穩腔的實驗設計，設計了開環和閉環兩套控制系統。通過使用美國通用掃描公司的掃描頭控制bbo晶體的轉動，用ccd對bbo - opo輸出波長進行標定，實現了bbo - opo調諧系統的閉環控制，相對波長調諧誤差小於0 . 04 ，並給出了354 . 7nm泵浦的類相位匹配bbo - opo輸出波長隨晶體轉角變化的理論和實驗曲線。 -
To meet the increased regulatory requirements on emission and fuel economy, the electronic control units ( ecu ) for engine is becoming more and more complex, which also makes its exploitation more difficult. the traditional method of debugging ecu through bench tests is almost outdated for its high cost, long exploitative period, unstable environment, etc. the substitute is found to be hardware - in - loop simulation
為了滿足日趨嚴格發動機排放和燃油經濟性法規限制，發動機電控系統（ ecu ）的功能復雜程度在不斷提高，相應的開發難度也在不斷加大，通過臺架試驗來逐步調試ecu的傳統方法由於耗費大量人力物力，開發周期長，調試環境不穩定、可重復性差等缺點，已難以適應ecu系統快速升級換代的需求，對此可採用硬體在環模擬技術予以解決。 -
An unstable process is transformed into a minimum - phase system through mirror - injection, then solve the robust controller using closed loop gain shaping algorithm
通過鏡像映射將非穩定過程轉換成最小相位系統，然後用閉環增益成形演算法求解魯棒控制器。 -
Because its largest singular value curve is identical before or after the unstable process is mirror - injected, and the closed loop gain shaping algorithm constructs directly the robust controller using parameters having engineering sense according to the shape of the singular value curves of the robust performance index, the designed controller has equally robustness to the unstable process
由於非穩定過程在鏡像映射前後的奇異值曲線相同，而閉環增益成形方法直接根據魯棒性能指標的奇異值曲線形狀用閉環系統具有工程意義的參數構造出魯棒控制器，故該控制器對非穩定過程同樣具有魯棒性。 -
In this paper, dynamic inversion control law is designed to eliminate its global non - linearization and unstable aerodynamic force etc. and based on the time - scale separation principle, the control system can be divided into fast loop and slow loop. but there are still lots of unknown disturbances that may cause great damages to stability when flying
由於在飛行過程中大范圍非線性、具有非定常氣動力等特性，本文採用了非線性動態逆控制律來構成全局線性化的性質，根據時標分離的原則，設計了空天無人飛行器的快迴路和慢迴路控制器。 -
Since a magnetic levitation system is usually strongly nonlinear and open - loop unstable, it is an important task to construct a hign performance feedback controller to control the position of the levitated object
由於磁懸浮系統有很強的非線性及開環不穩定性，所以設計一高性能的反饋控制器來控制懸浮目標是一件非常重要的任務。
