Based on the chaotic theory and non-linear system theory, a new active flow control technology-the synthetic jet technology, appeared several years ago 基于混沌理論及非線性系統(tǒng)特征的合成射流技術(shù)是國際上近幾年提出的一種全新的流動主動控制技術(shù)。
In this paper we deal with two aspects of applied mathematics, one is digraph theory and the other is infinite-dimensional linear system theory 本文將研究兩個方面的內(nèi)容:有向圖理論與無窮維線性系統(tǒng)。這兩個方面是應(yīng)用數(shù)學(xué)中的兩個非常重要的研究領(lǐng)域。
Based on the model, the decoupling design of the system by the method of nonlinear decoupling are presented and a linear model is resulted . then, linear system theory can be used to analysis and design the system 在所建模型的基礎(chǔ)上,本文用非線性解耦方法對其進(jìn)行了解耦設(shè)計,得到一個線性模型,這樣就可以用線性系統(tǒng)理論對其進(jìn)行分析和設(shè)計。
Now the subject of modeling and identifying various nonlinear systems has attracted many researchers . however, it is difficult for the classical identification methods based on the linear system or intrinsically linear system theory to provide satisfactory results 當(dāng)前,對各種非線性系統(tǒng)的建模、辨識己引起人們的廣泛注意,但是,使用建立在線性或本質(zhì)線性系統(tǒng)基礎(chǔ)上的傳統(tǒng)辨識方法難以獲得理想結(jié)果。
When irradiation response and dose are linear, total dose radiation and post-irradiation annealing at room temperature are determined for one random by choosing absorbed dose rate, and total dose effect at other absorbed dose rate can be predicted by using linear system theory 研究結(jié)果表明,輻射響應(yīng)與吸收劑量成線性關(guān)系時,在實(shí)驗室選用任一特定劑量率進(jìn)行總劑量輻射和輻照后室溫退火,可以通過線性響應(yīng)理論模擬其它劑量率輻射下的總劑量效應(yīng)。
Furthermore, the well-known separation principle for designs of controllers and observers in linear system theory are proved to be hold for fuzzy large-scale systems considered in this dissertation, which is important for analysis and design problems of controllers and observers of interconnected fuzzy large-scale systems 并證明了對于關(guān)聯(lián)模糊大系統(tǒng)而言,線性系統(tǒng)中著名的控制器及觀測器設(shè)計的分離原理也是成立的,這對于非線性關(guān)聯(lián)模糊大系統(tǒng)控制器與觀測器的分析與設(shè)計問題具有重要的意義。
This paper establishes the mathematic model according to the second law of newton and the foundation of the dynamics and analyses respective the force of cart and pendulum adopted the concept of " the equivalent cart " to linearization . the paper specialize the control ability of pendulum system using linear system theory and perform the control of the inverted pendulum applying state feedback theory through pole collocate 本文首先利用牛頓第二定律及相關(guān)的動力學(xué)原理建立二級倒立擺的數(shù)學(xué)模型,對小車和擺分別進(jìn)行受力分析,并采用等效小車的概念進(jìn)行線性化處理,并運(yùn)用線性系統(tǒng)理論分析了這個系統(tǒng)的能控性,提出了應(yīng)用狀態(tài)反饋理論,通過極點(diǎn)配置實(shí)現(xiàn)對倒立擺的控制。
