中文拼音 [kuìdiàngǎn]
饋電桿
英文
feeder pillar-
Also it is discussed how to improve loading performance and the actual results using invariance theory. by the feedforward signals of velocity and acceleration, it is expected to expend the bandwidth to 15hz or even higher and reduce the additional torque at 80 percent. in this thesis, i mainly explored the design theory of ehsls and made a lot of experiments on subsystems and the whole system
本文的目的就是設計、調試帶有彈簧桿緩沖結構的單通道電液伺服加載臺，通過試驗比較、驗證不同控制演算法的工程實際效果；分析和研究應用結構不變性原理如何改善加載系統的動態性能，目的是通過引入速度和加速度的復合前饋信號將系統的動態頻帶提高到15hz左右，並且有效的抑制力加載系統固有的多餘力矩，抑制比要達到80以上。Firstly, for the intelligent structure ' s active bars, a constant output velocity feedback control law is dissipation energy due to control action and the optimal mathematical model with the reliability constraints on dynamic stress and displacement was built
以直接輸出速度反饋作為閉環控制律，基於最大耗散能準則，建立了以主動桿配置位置和控制系統增益為設計變量，具有動力響應（應力響應和位移響應）可靠性約束的壓電智能桁架結構主動桿優化配置的數學模型。Using the optimization control method of the moderm control theories, the time - varying control and output - feedback control the authors study the variable structure active control over the rotor vibration with sma, especially the method of restraining the transient response of the rotor vibration. they get the rule of the optimum control force and the optimum control electric current and discuss the influence of variable stiffness on the total system stiffness through analyzing the structure of sma controller. they also indicate the shortcoming of the orthodox design method of a controller, especially the imbalance phenomenon caused by the lack of the rod stability, and propose a new method for improvement and items which ought to be paid attention to in the design stage
運用現代控制理論中的最優控制方法，引入時變控制和輸出反饋控制，研究利用形狀記憶合金對轉子振動進行變結構主動控制，特別是抑制轉子振動的瞬態響應的方法，得出了最優控制力和控制電流的強度變化規律；通過分析形狀記憶合金動作器的結構，探討了變剛度支承對系統總體剛度的影響，指出了傳統設計方法的不足之處，特別是由壓桿穩定性不足引起的失穩現象，並提出了改進的方法和在設計中值得注意的問題
