當(dāng)前飛行器主要的控制方法是基于近似時(shí)不變線性系統(tǒng)的頻域分析法(如pid控制) ，這種方法的優(yōu)點(diǎn)是簡(jiǎn)單且易于穩(wěn)定性和魯棒性分析，但它所達(dá)到的低性能和低效率卻轉(zhuǎn)化成了飛行器控制過(guò)程的附加載荷，還遠(yuǎn)不夠滿足當(dāng)前飛行器控制的要求。 - These roof structures are generally in high turbulent regions , then wind loads become important to these structures . commonly , wind - induced response is analysed in frequency domain method . but the contributions of those high order models are omitted owe to the complexity of analyse themselves
分析結(jié)構(gòu)風(fēng)致響應(yīng)時(shí)一般采用頻域法，而頻域法中采用常規(guī)的模態(tài)分析方法? ?振型截?cái)喾〞r(shí)，往往因?yàn)閷?duì)高階振型本身分析的復(fù)雜性而忽略了高階振型對(duì)結(jié)構(gòu)響應(yīng)的影響，使得計(jì)算的結(jié)果缺乏合理性。 - ( 2 ) for linear systems with time - varying delays both in state and control , and subject to norm - bounded parameter uncertainties , the problems of robust stabilization and robust h control are studied and delay independent results are derived by constructing proper lyapunov function to deal with the time - delay , also by using riccati equations method and inequalities transformations to deal with the uncertainties . according to the transform function of the system , frequency domain method and time domain method are combined together to analyze the robust h control problem of the uncertain time - delay system
