Forthermore , because of non - linear factors exist in control system , it is very important to decide how to choose a propriety control law 另外,控制系統(tǒng)本身有很多的非線性因素,所以選擇合理的控制規(guī)律也很重要。
A new method is proposed to study a large - scale power station structure in this paer , which is a time history response analysis method with considering non - linear factors for structure analysis 本文提出一種新的分析方法,即采用地震時程分析法并考慮材料的非線性因素,對某大型水電站廠房結(jié)構(gòu)進行抗震研究。
The linear factor is better than 0 . 9999 for y rays and 0 . 9995 for electron beams . it ' s esr response is increased in 0 . 26 % / ? in the range of 15 ~ 50 ? for irradiation temperature , no evident change found for different dose ranges 在輻照溫度15 50 、照射的劑量5 50kgy范圍內(nèi),溫度每升高1 ,其esr響應值升高0 . 26 ,且未發(fā)現(xiàn)隨吸收劑量的不同而有明顯的改變。
In this paper , taking thewh20s flight simulator as research object , application of variable structure control for flight simulator is discussed . first , based of researching the flight simulator ’ s control system , and the problems in the flight simulator ’ s low - speed performance , continuous time variable structure control is researched . then , the paper analyses the non - linear factors ’ effect especially the friction factor ’ s effect to the flight simulator 首先在分析轉(zhuǎn)臺的控制系統(tǒng)以及轉(zhuǎn)臺在低速時存在問題的基礎上,研究了連續(xù)時間系統(tǒng)的變結(jié)構(gòu)控制,分析了非線性因素特別是摩擦力矩對轉(zhuǎn)臺的影響,并對lugre摩擦模型做了研究,繼而將pid與變結(jié)構(gòu)控制結(jié)合起來進行了研究,在仿真的基礎上應用于wh20s轉(zhuǎn)臺的實際控制系統(tǒng),取得了較好的效果。
The time - related expression of stain along the crack - tip extension line was given from the use of the elastic - viscoelastic correspondence principle and standard linearity body model and the non - linear factors , which caused the gradual difference between the theoretical and actual value with the increase of time , were analyzed 應用廣義彈性?粘彈性對應原理,給出了線粘彈性體裂尖延長線應變值隨時間變化的表達式,分析導致理論與實驗情況隨時間增加產(chǎn)生偏差的非線性因素。
