摘　　要：为满足复杂工况下结构振动测试、控制、分析、实验教学及主动振动控制算法研究的实际需求,基于FPGA设计了一套4面固支薄板结构、调理电路和惯性作动器的多源干扰智能结构振动实验教学平台。针对系统存在的模型不定性、边界条件复杂、时延等问题,在该平台开展振动主动控制技术的验证。平台基于自抗扰控制算法和Verilog语言搭建,精度高、开放性强,加深学生对于振动信号的产生、采集以及控制方法的理解,对自抗扰思想的传播起到了积极意义。In order to satisfy the testing,control,analysis,experimental teaching and active vibration control algorithms requirements of vibration suppression for practical structures under complex working conditions,an intelligent structural vibration experimental teaching platform subjected multisources disturbances is designed,and applied in teaching practice.It consists of an FPGA board,allclamped plate structure,conditioning circuit and inertia actuator in this paper.Aiming at the problems of model uncertainties,complexity of boundary conditions and time delay existing in the system,the experimental platform carries out the verification of vibration active control technology.The experimental platform is built based on active disturbance rejection control and Verilog language,with high precision and strong openness.It significantly deepens students’understanding of the generation,acquisition and control methods of vibration signals.It also plays a positive role in the spread of the idea of active disturbance rejection control.
