Rate-dependent modeling and tracking control of giant magnetostrictive actuators

  • 摘要: 利用Hammerstein模型对超磁致伸缩作动器(GMA, Giant Magnetostrictive Actuators)进行建模, 分别以改进的Prandtl-Ishlinskii(MPI, Modified Prandtl-Ishlinskii)模型和外因输入自回归模型(ARX, Autoregressive model with exogenous input)代表Hammerstein模型中的静态非线性部分和线性动态部分,并给出了模型的辨识方法.此模型能在1~100 Hz频率范围内较好地描述GMA的率相关迟滞非线性特性.提出了前馈逆补偿和比例-微分-积分(PID, Proportional-Integral-Derivative)反馈相结合的复合控制策略.实时跟踪幅值为16 μm的单一频率和复合频率正弦参考输入信号, 均方根误差小于1 μm, 相对误差小于10%, 证明了控制策略的有效性.
