锆钛酸铅镧驱动器作为光致形变驱动器的一种，已广泛应用于微驱动系统和光致叠层柔性结构的主动振动控制。然而，单贴片铅锆钛酸镧驱动器光形变响应慢，极大地影响了其应用。本文采用实验方法研究了导致锆钛酸铅镧执行器响应缓慢的主要因素。开灯状态下的温度升高以及关灯状态下的残余光电压和光变形被认为是导致锆钛酸铅镧致动器响应缓慢的主导因素。为了使锆钛酸铅镧驱动器获得更好的驱动能力，本文提出了一些通过减弱温度升高的影响、消除残余光电压和光变形的有效解决方案并进行了实验验证。考虑到本文提出的有效解决方案，提出了一种基于多补丁组合的新型光学驱动机制。
Lead lanthanum zirconate titanate actuators taken as one type of photo-deformable actuators have been widely applied for micro-driven systems and active vibration control of photostrictive laminated flexible structures. However, the slow response of photodeformation of single patch lead lanthanum zirconate titanate actuator greatly affects its application. In this article, the main factors for the slow response of the lead lanthanum zirconate titanate actuator are investigated using experimental method. The increasing temperature during light on state and the residual photovoltage and photodeformation during light off state are considered as dominant factors causing the slow response of the lead lanthanum zirconate titanate actuator. To gain a better driving capability of lead lanthanum zirconate titanate actuator, some effective solutions through weakening the effect of increasing temperature and eliminating residual photovoltage and photodeformation are proposed and experimentally validated in this article. Considering the effective solutions proposed in this article, a novel optical driving mechanism based on multi-patches combination is proposed.
