目前,在引进的染整设备中,采用多单元同步传动系统的占有相当大的比例。组成同步系统的单元机多数为电压负反馈加电流正反馈控制的 KZ-D 系统,或为转速、电流双闭环系统。本文对日本引进的 SST 短环烘干机同步系统进行计算机仿真及动态分析,并探讨其设计原则。1.原理简介SST 短环烘干机相邻两单元机组成一同步系统(简称从动机同步系统)。从动单元机具有电压负反馈、电流正反馈控制的变流控制装置 DS—100,简称(DS—100)从动机。其原理框图如图1所示。
At present, in the introduction of dyeing and finishing equipment, the use of multi-unit synchronous transmission system occupies a large proportion. Most of the units that make up the synchronous system are KZ-D systems with negative feedback of voltage and positive feedback of current control, or dual closed-loop system with speed and current. This article carries on the computer simulation and the dynamic analysis to the synchronous system of SST short cycle dryer imported from Japan, and discusses its design principle. 1. Principle Introduction SST short-ring dryer adjacent two units form a synchronous system (referred to as the motivation synchronization system). Slave unit has voltage negative feedback, current feedback control of the converter control device DS-100, referred to as (DS-100) from the motivation. The block diagram shown in Figure 1.
