Simulations are formed for the passive control system and active control system with different controller ( 4 )比較了被動控制系統(tǒng)與主動控制系統(tǒng)的性能。
The principal content in this paper is the study for passive control systems of earthquake response of structure using sma damper 本文的主要內(nèi)容是sma耗能器對建筑結(jié)構(gòu)地震反應(yīng)被動控制的研究。
Then the performance of the active and passive control system is compared . the results show that active control system has superior performance over the passive control system 結(jié)果表明,添加主動控制器后,主動控制系統(tǒng)的性能與被動控制系統(tǒng)相比得到了明顯的改善。
Traditional vehicle suspension system is passive control system . it is designed for certain special road surface and vehicle riding state , which vibration dampers have fixed damping characteristic . when the road surface and vehicle riding state overage the design conditions , the damping effect of the passive control system will be depressed 傳統(tǒng)的車輛懸架系統(tǒng)是被動懸架系統(tǒng),是按某種特定的路面狀況和車輛運行狀態(tài)進(jìn)行設(shè)計的,其減振器的阻尼特性是不可調(diào)的,當(dāng)路面狀況和車輛運行狀態(tài)超出設(shè)計條件時,固定阻尼特性的被動懸架系統(tǒng)的減振效果將大為降低。
On the other hand the research about dry friction system response calculation method is limited in passive control system . in this article , the precise solution to the linear quadratic optimal control system with load is analyzed firstly , and then a gradually deduced response solution method of lq control dry friction system is brought forward 另外人們對干摩擦系統(tǒng)響應(yīng)計算方法的研究大都局限于不受外載的控制系統(tǒng),本文在研究外載作用下lq控制系統(tǒng)riccati方程精確解法的基礎(chǔ)上,也提出了干摩擦lq控制系統(tǒng)響應(yīng)計算的遞推求解方法。
