Based on a duralumin flexible beam with piezoelectric films attached, distributed parameter modal described by partial difference equations is builded, and then turned into a set of two order systems with the method of modal analyse. state feedback control and independent modal control is investigated. and simulation of the closed - loop system with thest two methods is performed in matlab
並用模態分析的方法，將系統的偏微分方程模型轉化成了模態模型；研究了狀態反饋和獨立模態方法；進一步完善了軟體界面以及軟體功能；在實際系統中，應用狀態反饋演算法，有效抑制了懸臂梁在受到外界瞬時脈沖擾動和激振引起的一階、二階模態振動。As it was, he saw gallingly, the incident would be rolled into the horst family annals, as a pivotal and eternally ramifying moment ? the time mommy ( and, as she would become, grammy ) was stung by a bee, and funny foreign - born grampa resourcefully saved her
現在事情到了這一步，他難堪地看到：這件事將作為極度關鍵永遠起轉折點作用的瞬間而載入霍斯特的家族史? ?媽咪（或者說，奶奶，她反正要當奶奶的）被蜂蟄時，模樣滑稽出生於外國的爺爺多麼機智地救了她。This paper presents an assur - group method for the kinematic analysis of plannar cam mechanisms. during inversion, each instantaneous cam mechanism is transformed into an assur - group in this method
該方法是把反轉中的凸輪機構的各個瞬時機構轉化為桿組，通過對桿組的分析完成對凸輪機構從動件的運動分析。By use of - perturbation method with spatial discretization, the hydraulic transient system controlled by quasilinear partial differential equation was converted to a time - continuous linear system, so that the inverse problem of hydraulic transients under limited pressure could be sol ed with the optimal control theory for time - continuous systems
採用-攝動法並經過空間離散，將由擬線性偏微分方程式控制制的有壓瞬變流系統轉化為時間連續線性系統，從而使有壓瞬變流限壓控制反問題能應用時間連續系統最優控制理論來求解。We have finished the semi - phsical simulation on the single axis turfing platform, which included on board prototype computer, optic fiber gyro and reocaon wheel which saturation chamaeristic has been taken into account
本文採用瞬時歐拉軸控制演算法，在星載計算機原理樣機的基礎上，考慮反作用飛輪的飽和特性，根據所選擇的反作用飛輪和光纖陀螺，在單軸氣浮轉臺上進行半實物模擬驗證。" some members considered that given the pace of change of the modern world and the trend of globalization, we might not need to make specific choices for the next 20 or 30 years. instead, we should have some rolling plans and built - in mechanism in our system to allow flexibility so that we could always be prepared to adapt to the fast - changing needs of the society
部分委員認為，由於現今世界瞬息萬變，以及全球一體化的趨勢，我們或許不需要為往後二、三十年做一些具體的選擇，反而，我們要有一些延展的計畫以及建立一些機制，使我們的系統更為靈活，為適應急劇轉變的社會需求，隨時作好準備。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
