基于Simulink的位置正馈振动主动控制

基于Simulink的振动主动控制,用Simulink框图设计位置正馈补偿滤波器.将实际模型置于仿真系统进行半实物仿真控制.通过位置测量、对位控制,将受控结构位置正馈至控制器,再将控制器位置正馈给控制结构,控制其振动.并以交互界面修改滤波器参数,在Simulink中,通过定义封装模块实现计算机与数据采卡的通信.

Active Vibration Control for Positive Position Feedback Based on Simulink

For active vibration control for positive position feedback based on Simulink, positive position feedback (PPF) filter is designed using the block diagram in the Simulink, and the system model is putted in simulated system to control the simulation of hardware-in-the-loop. The position of controlled structure was positively fed back to controller according to position measure and contraposition control, and position of controller was positively fed back to control structure to control the vibration of controlled structure. The corresponding parameter of the PPF filter was modified through the GUI, and the communication between computer and data acquisition card was realized through encapsulated module was defined in Simulink.
