| 摘 要： | 通过建立换能器和负载的等效M-C-K数学模型,分析了负载对超声波换能器的动态影响,并在Matlab软件中建立换能器的传递函数与仿真模型。提出了PID和H∞振动控制算法,其是建立在Matlab的Simulink仿真。通过对比分析发现,PID和H∞算法可实现准确、快速的控制效果。最后,对理论和仿真计算进行了实验验证。

| Abstract: | In this paper,a numerical vibration model is established by a mass-damper-elastic component. The loaded effect on the dynamics of the ultrasonic transducer is investigated. The transfer function of transducer is attained and the calculation simulation model is carried out in Matlab. The PID and H∞ algorithm for vibration control is established and simulated in the Matlab Simulink ,and found that the PID and H∞ algorithm can achieve the accurate and fast control result. Finally ,some experiments to verify the theory and simulation calculation is carried out. |
