Test and Simulation of Double Layer Vibration Isolation Based on dSPACE

由于控制系统中控制器输出到误差信号之间存在功率放大器、作动器以及误差传感器等,误差通道可能会使信号的幅值和相位发生改变,甚至改变信号的频率。运用FxLMS自适应控制算法,基于误差通道离线辨识,进行控制系统的仿真。基于dSPACE半实物仿真系统搭建试验平台,完成单频和双频信号的自适应主动控制,取得显著控制效果。

Since there are power amplifiers,actuators and error sensors between the controller output and the error signals in control systems,the error channel may cause the amplitude,phase and frequency change of the signals.In this paper,Fx LMS adaptive control algorithm based on the error channel off-line identification is used for simulation of the control system.Based on dSPACE hardware-in-the-loop simulation system,a self-adaptive active control system for singlefrequency and dual-frequency signals is built,and a significant control effect is achieved.
