【摘要】 针对不光滑非单值对应的非线性压电陶瓷的迟滞特性,提出了采用灰色理论中的累加生成(AGO)方法,将压电陶瓷的非负多值对应的输入与输出特性的数据转换为单值对应的新数据,再通过神经网络建立压电陶瓷的迟滞特性模型。仿真实验结果表明,用该方法建立迟滞特性对象的模型是有效的。更多还原

【Abstract】 The neural network hysteresis model of piezoceramic actuator is presented by using accumulated generating operation(AGO)of gray theory in which AGO transforms the multi-valued function of hysteresis into the single-valued function. Simulation and experimental results show that this new approach for identification of the nonlinear piezoceramic actuator is effective and of high precision.更多还原
