摘要
分析并设计出多输入多输出(简称MIMO)随机振动控制算法,讨论了MIMO随机振动控制中的几点关键技术如传函矩阵估计、三帧搭接法等。通过以三轴六自由度液压振动台系统为典型被控对象,建立三轴六自由度液压振动台随机振动控制仿真系统。仿真结果表明,经过多帧均衡后,MIMO随机振动控制能够取得较好的控制效果,其控制容差均在±3dB以内。
The MIMO random control method in the three aixs-six DOF shaking table was analyzed, and some important techniques which are the estimation of the transfer function matrix and the three-frame joining method for drive signals were discussed. The three aixs-six DOF shaking table was looked as the MIMO random vibration control object, the MIMO random vibration control simulation system for the three aixs-six DOF shaking table was built. Simulation result shows that the control result is satisfied and the control spectums are within the ±3dB tolerance error.
