［摘要］創(chuàng)新地將調(diào)諧質(zhì)量阻尼器(TMD)和主動(dòng)調(diào)諧質(zhì)量阻尼器(ATMD)引入到動(dòng)力設(shè)備作用下某三層結(jié)構(gòu)振動(dòng)控制研究之中，其中動(dòng)力設(shè)備采用兩級(jí)隔振體系。對(duì)于ATMD控制體系，主動(dòng)算法采用基于局部狀態(tài)觀測(cè)的LQG控制理論，并引入新型的群智能算法——粒子群優(yōu)化算法（PSO）以對(duì)權(quán)值矩陣進(jìn)行優(yōu)化計(jì)算，適應(yīng)值函數(shù)定義為模擬時(shí)程內(nèi)結(jié)構(gòu)層的絕對(duì)位移之和。數(shù)值計(jì)算結(jié)果表明，將TMD或者ATMD應(yīng)用到動(dòng)力設(shè)備致結(jié)構(gòu)振動(dòng)控制之中可行，且ATMD對(duì)結(jié)構(gòu)整體而言具有更加優(yōu)異和穩(wěn)定的控制性能。［關(guān)鍵詞］TMD; ATMD; 動(dòng)力設(shè)備; 振動(dòng)控制; LQG; 權(quán)值矩陣; PSO; 適應(yīng)值函數(shù)中圖分類(lèi)號(hào)：TU112.41 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)19-0048-05

In the ATMD control system, local state observation based on linear quadratic gauss (LQG) control theory was applied to the active calculation method, and a novel swarm intelligence method—particle swarm optimization (PSO) was utilized to pursue an optimal weight matrix. The sum of absolute displacements of all structural layers in the simulated time history was defined as the fitness function. Numerical calculation results show that applying TMD or ATMD to structural vibration control induced by power equipments is feasible, and ATMD can perform a much better and more stable control effect for the whole structure.Keywords: tuned mass damper(TMD); active tuned mass damper(ATMD); power equipment; vibration control; linear quadratic gaussian(LQG); weight matrix; particle swarm optimization(PSO); fitness function
