In this research, the nonlinear, double-dynamic Taguchi method was used as design and analysis methods for a high-precision positioning device using the combined piezo-voice-coil motor (VCM) actuator. An experimental investigation into the effects of two input signals and three control factors were carried out to determine the optimum parametric configuration of the positioning device. The double-dynamic Taguchi method, which permits optimization of several control factors concurrently, is particularly suitable for optimizing the performance of a positioning device with multiple actuators. In this study, matrix experiments were conducted with L9(3(4)) orthogonal arrays (OAs). The two most critical processes for the optimization of positioning device are the identification of the nonlinear ideal function and the combination of the double-dynamic signal factors for the ideal function's response. The driving voltage of the VCM and the waveform amplitude of the PZT actuator are combined into a single quality characteristic to evaluate the positioning response. The application of the double-dynamic Taguchi method, with dynamic signal-to-noise ratio (SNR) and L9(3(4)) OAs, reduced the number of necessary experiments. The analysis of variance (ANOVA) was applied to set the optimum parameters based on the high-precision positioning process.
在本研究中，非线性双动态田口方法被用作一种采用压电音圈电机（VCM）组合式致动器的高精度定位装置的设计与分析方法。针对两个输入信号和三个控制因素的影响开展了实验研究，以确定定位装置的最佳参数配置。双动态田口方法允许同时优化多个控制因素，特别适用于优化具有多个致动器的定位装置的性能。在本研究中，采用L9(3(4))正交阵列（OA）进行了矩阵实验。定位装置优化的两个最关键过程是识别非线性理想函数以及为理想函数的响应组合双动态信号因素。将VCM的驱动电压和PZT致动器的波形幅度组合成一个单一质量特性，以评估定位响应。双动态田口方法与动态信噪比（SNR）和L9(3(4)) OA的应用减少了所需实验的数量。基于高精度定位过程，应用方差分析（ANOVA）来设置最佳参数。
