Adaptive Vibration Active Control Simulation Based On MATLAB And Veristand And LabVIEW Interface Design

With rapid developement of active virabtion control in the last few decades, its application in the industries has been unprocceedingly comprehensive and profound.VeriStand software platform provided by National Instrument is introduced in the active vibration control simulation system based on LMS algorithm to satisfy the demand on real-time control. Lab VIEW is used to design and create the user graphic interface considering its adavantages in graphic programming and human-computer interaction techniques. The paper first introduced the key features of VeriStand and elaborated developement process and applications of VeriStand platform. The principles of LMS-based adaptive algorithm were derived and used to program the Simulink model, which was later compiled into NI VeriStand for simulation. Single-channel and four-channel simulation were conducted to testify proposed LMS-based adaptive algorithm and the simulation program.Next,according to the practical requirement of active vibration control, a graphic user interface is designed and visualized to given the power tools of LabVIEW.Then the ideas of queue and event structure were brought in to process the experimental data. And LabVIEW here is utilized to establish the producer/customer loop between the master and slave in the system, which significantly boost the efficiency of the program and ensure the accuracy and high efficiency.The result of simulation with LMS-based algorithm indicated that the control system developed with MATLAB and VeriStand performed well in real-time active vibration suppression. The effectiveness and stablity of the algorithm as well as the simulation program was justified,which suggested a potentially general application of this adaptive control algorithm in the industries and academic reseaches.
