The semi - active logic control algorithm was proposed , which includes six kinds of semi - active logic control method . they are the semi - active logic control method a , b and c for single mr damper , the semi - active logic control method d , e and f for multiple mr dampers . a series of numerial simulation and experimental investigations on the seismic responses of the tall building with a podium structure using single damper / multiple mr dampers were first carried out on the seismic simulator in the hong kong polytechnic university on 2002 - 2003 針對(duì)帶裙房高層建筑地震反應(yīng)的鞭梢效應(yīng)問題,以瞿偉廉教授和徐幼麟教授提出的“ er mr智能阻尼器耦聯(lián)的帶裙房高層建筑結(jié)構(gòu)地震反應(yīng)的半主動(dòng)控制”理論為起點(diǎn),采取理論分析、計(jì)算機(jī)仿真和地震模擬振動(dòng)臺(tái)試驗(yàn)等研究手段,首次將基于泛布爾代數(shù)的邏輯控制方法引入結(jié)構(gòu)控制領(lǐng)域,提出了半主動(dòng)邏輯控制方法,包括單mr阻尼器半主動(dòng)邏輯控制a 、 b 、 c和多mr阻尼器半主動(dòng)邏輯控制d 、 e 、 f等六種。
The performance and effectiveness of the semi - active logic control algorithm could only depend on the control algorithm itself without structural system model and is not affected by external disturbance , in which the analysis is simplified and the control performance is enhanced . the semi - active logic control algorithm has the high adaptability for different kinds of ground excitations . the effectiveness and efficiency of the proposed semi - active logic control algorithm was higher than those of the clipped - optimal algorithm , which is one of the most popular control algorithms used at present for mr dampers 半主動(dòng)邏輯控制方法不依賴結(jié)構(gòu)體系模型和外界擾動(dòng)影響,只依賴于邏輯控制算法自身,簡化了分析過程,增強(qiáng)了控制效果,且對(duì)不同激勵(lì)的適應(yīng)性強(qiáng),比目前廣泛應(yīng)用的部分最優(yōu)控制算法的控制效果和魯棒性好,是一種新的具有工程應(yīng)用價(jià)值的結(jié)構(gòu)智能半主動(dòng)控制方法。
The experimental results on seismic simulator verify that the mr damper in the passive off mode provided the information on the minimum effectiveness of the damper if the external power was cut off , in which the seismic responsesof the tall building and podiun structure were reduced . when the mr damper worked in the six kinds of semi - active logic control methods , the seismic responses of the two building were further reduced compared with those when the mr damper worked in the passive off mode 地震模擬振動(dòng)臺(tái)試驗(yàn)結(jié)果表明: mr阻尼器的passiveoff方式是外部電源被切斷時(shí)的最低控制效果,能消除原結(jié)構(gòu)地震反應(yīng)的鞭梢效應(yīng),并使主樓和裙房的地震反應(yīng)有一定的減少,六種半主動(dòng)邏輯控制方法的減振效果比passiveoff方式更好,多mr阻尼器控制的效果優(yōu)于單mr阻尼器。
