论文摘要
我们讨论了一种算法，该算法通过修改用于驱动执行器的电压波形的相位，从而消除了双摩尔压电执行器的周期性非线性。提出的过程允许对执行器组的运动进行单独优化，以便获得所需的属性（例如特定的步骤或最大力）。实验研究了在不同载荷下的双足球驱动器的最终响应。如果运动是可重现的，则可以将优化过程应用于依靠内部周期过程的其他执行器，并且仅受测量噪声或制造公差的限制。
We discuss an algorithm that eliminates the periodic non-linearity of a bimorph piezo actuator by modifying the phase of the voltage waveforms used for driving the actuator. The procedure presented allows for a separate optimization of the motion of the actuator groups in order to obtain the properties desired (such as a specific stepsize or maximum force). The resulting response of a bimorph piezo drive, also under different loads, is experimentally investigated. The optimization process can be applied to other actuators relying on internal periodic processes, if the motion is reproducible, and is limited by measurement noise or manufacturing tolerances only.
