摘　　要：电动伺服系统由于结构的柔性特性影响,会出现系统谐振现象,当指令输入含高频成分时谐振往往更容易发生。针对这一现象,本文对S型曲线和阶跃曲线两种指令输入的时域特性和频域特性进行了研究,在理论上论证了S型曲线相对于阶跃曲线的诸多优势。最后通过仿真,验证了分析的正确性。Due to the flexible characteristics of structure,resonance phenomenon will appear in the electric servo system.When the instruction contains high-frequency,resonance is often more likely to occur.In response to this phenomenon,this article studied the time domain characteristics and frequency domain characteristics of the S-type curve and the step curve,which theoretically demonstrated the many advantages of the S-type curve compared to the step curve.Finally,the accuracy of analysis was verified through simulation.
