用8098单片机实现张力控制的直流拖动系统

Implementing Tension Control of DC Drive System by Using 8098 Microprocessor

间接张力控制系统中，卷径D、动静态张力补偿电流计算复杂，用模拟乘除器实现起来误差大、漂移严重，很难实现精确的张力控制。本文介绍一种用8098单片机做卷径和张力补偿电流计算，用常规模拟调节器实现电流和磁通控制的系统，这一系统具有结构简单、卷径计算精确、张力控制精度高和调整方便等特点。

In indirect tension control, the calculating of roll diameter、dpomic and statics compensation current of tension is complex. By using analog multiplier and divider, there will be large error and drift and therefore it difficult to implement accurate tension control. The article infroduces a tension control system, in which, the roll diameter and tension compensation calculstion are implemented by use of 8098 microprocessor the current and inagnetic flux controls are by use of analog requlators. The system has the features of simple structure,accurate calculating and simple adjustment.
