Abstract
Piezoelectric materials, with their unique electromechanical coupling properties, have demonstrated significant application value in the field of precision driving technology. As modern industry increasingly demands high-precision, fast-response, and miniaturized driving systems, piezoelectric driving technology has gradually become a research hotspot. This study aims to explore the application potential of piezoelectric materials in precision driving and investigate methods for performance optimization. By combining theoretical analysis with experimental validation, the driving characteristics of two types of materials, namely piezoelectric ceramics and piezoelectric polymers, were studied in depth, and a novel driver structure based on the converse piezoelectric effect was designed. The results indicate that this driver exhibits excellent resolution and stability at the micro-nano scale, achieving displacement accuracy at the sub-nanometer level while maintaining high energy conversion efficiency. Furthermore, an improved control algorithm was proposed, effectively reducing errors caused by nonlinear effects and significantly enhancing the dynamic performance of the system. A key innovation of this study lies in the integration of novel material properties with advanced driver structural design, providing new insights for the development of high-performance precision drivers. The research not only expands the application scope of piezoelectric materials but also lays a theoretical and practical foundation for technological advancements in related fields.
