Abstract
Abstract The dynamic performance of the hydraulic system depends on the dynamic characteristics of the servo valve. In this article, the control characteristics of the piezoelectric servo valve are studied theoretically and experimentally. The mathematical model of the system is established by considering the influence of the piezoelectric servo valve, the influence of the pipeline, and the interaction between them. The frequency response characteristics of the system and the influence of the pipeline parameters on the control characteristics of the system are discussed. The simulation results are compared with the experimental results to verify the accuracy and efficiency of the piezoelectric servo valve dynamic model established in this article.
