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。
The innovative tuned mass damper (TMD) and active tuned mass damper (ATMD) are introduced into the vibration control of a three-story structure under the action of power equipment. The power equipment adopts two-stage vibration isolation system. For the ATMD control system, the active algorithm uses the LQG control theory based on local state observations and introduces a new type of swarm intelligence algorithm - Particle Swarm Optimization (PSO) to optimize the weight matrix. The fitness function is defined as the simulation time history The sum of the absolute displacements of the inner structural layers. Numerical results show that it is feasible to apply TMD or ATMD to structural vibration control of power plant, and ATMD has more excellent and stable control performance for the whole structure.
