摘要
本文以压电陶瓷促动器构建并联六自由度减振平台,采用NI Compact-RIO实时控制系统和Fx-LMS自适应控制算法进行振动主动控制,对次级通道辨识方法和主动控制算法进行了模拟仿真,并搭建主动减振控制系统进行实验验证。仿真与实验结果表明,设计的主动减振控制系统对于7~50 Hz范围内的低频微振动有很好的控制效果。
A parallel 6-DOF vibration isolation platform was built with piezoelectric ceramic actuators.And the NI Compact-RIO real-time control system and Fx-LMS adaptive filtering control algorithm were used for active vibration control.The secondary channel identification method and active control algorithm were simulated,and the active vibration control system was built for experimental verification.The simulation and experimental results show that the designed active vibration control system has a good control effect on the low-frequency micro-vibration at the range of 7 Hz to 50 Hz.
