［摘要］创新地将调谐质量阻尼器(TMD)和主动调谐质量阻尼器(ATMD)引入到动力设备作用下某三层结构振动控制研究之中，其中动力设备采用两级隔振体系。对于ATMD控制体系，主动算法采用基于局部状态观测的LQG控制理论，并引入新型的群智能算法——粒子群优化算法（PSO）以对权值矩阵进行优化计算，适应值函数定义为模拟时程内结构层的绝对位移之和。数值计算结果表明，将TMD或者ATMD应用到动力设备致结构振动控制之中可行，且ATMD对结构整体而言具有更加优异和稳定的控制性能。［关键词］TMD; ATMD; 动力设备; 振动控制; LQG; 权值矩阵; PSO; 适应值函数中图分类号：TU112.41 文献标识码：A 文章编号：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
