The Model of VCR Drum Software Servo System and Determination of Relative Parameters

提出了用于录像机软件伺服控制系统设计的鼓伺服系统模型；针对这种模型计算和测试了所需要的参数，又提出了用计算机辅助设计和分析技术建立三维实体模型，快速准确计算磁鼓组件物理参数的新方法，确定出相关系数；并用实验验证了理论分析计算结果，最后建立了鼓电机的等效电路模型。

This paper presents a model for designing VCR drum software servo system. The relativecofficients are tested and calculsted. To calculate the physical parameter of drum module quickly andprecisely, a new method which uses the technology of computer aided design and analysis is provided to builda three-dimension solid model. All the theoretical calculations are rested in experiment. Consequently, theequivalent circuit of the drum motor is developed.
