掺镧锆钛酸铅（PLZT）陶瓷作为紫外光驱动的光控微致动器，在微驱动领域具有潜在的应用前景。针对PLZT陶瓷光致伸缩响应慢的问题，提出了一种基于PLZT陶瓷的新型光电混合驱动光控驱动器。在PLZT陶瓷反常光伏效应模型的基础上，建立了光控驱动器的数学模型。基于所建立的数学模型和PLZT陶瓷的光电压实验，研究了微驱动器的驱动特性。通过实验获得了基于PLZT陶瓷的光电混合驱动微驱动器的驱动曲线，验证了光控微驱动器设计的合理性和可行性。分析和实验结果表明，基于PLZT的新型光-静电混合驱动的光控驱动器能够实现高效、精确的位移控制，且响应速度快。另外，基于新型光电混合驱动的驱动方法具有非接触控制、远程控制、无电磁干扰等优点。
The lanthanum-doped lead zirconate titannate (PLZT) ceramic has shown its potential applications as light-controlled micro actuators activated by ultraviolet light for the photovoltaic effect in the field of micro-driven. Aiming to the slow response of photostriction of PLZT ceramic, the primary purpose of this article is to propose a light-controlled actuator with the novel opto-electrostatic hybrid driving based on PLZT ceramic. The mathematical model of the proposed light-controlled actuator is established on basis of the anomalous photovoltaic effect model of PLZT ceramic. The actuation characteristics of the micro actuator are investigated based on the established mathematical model and the experiments of the photovoltage of PLZT ceramic. Furthermore, the actuation curves of the micro actuator driven by opto-electrostatic hybrid driving based on PLZT ceramic are acquired to verify the rationality and feasibility of the light-controlled micro actuator design. So according to the analysis and experimental results, the light-controlled actuator driven by the novel opto-electrostatic hybrid driving based on PLZT can conduct the effectively and precisely displacement control with fast response speed. In addition, the driving method based on the novel opto-electrostatic hybrid driving has advantages of non-contact control, remote control and no electromagnetic interference, etc.
