【摘要】 研究基于神经网络的弹性连杆机构振动主动控制问题。设计了具有压电作动器与应变传感器的机敏机构实验装置及其控制系统。利用实验数据离线设计了动态递归神经网络控制器,并采用基于神经网络的直接自校正控制策略最终实现了机敏机构的振动控制,机构的动力学特性显著改善。
【Abstract】 This paper introduces the applications of Neural Networks into the active vibration control of Flexible Linkage Mechanisms.The smart mechanism featuring piezoceramic actuators and strain gauge sensors is designed and constructed. Using experimental samples,the Dynamic Recurrent Neural Network(DRNN)controllers are designed off-line.The smart mechanism is controlled on-line by means of the Neural Networks based Direct Self-Tuning Control strategy.As a result,the elastodynamic behavior of the smart mechanism is improved significantly.
