            <description><![CDATA[　在伺服系统的调试过程中，需要能够准确发送各种测试信号的正弦机。但通常使用的机电正弦机具有难以克服的机械传动空回、死区及波形失真和漂移、装订参数可重复性差等缺点。　　为了克服以上缺点，作者开发了8098数字正弦机。　　1　硬件组成　　8098数字正弦机采用MCS-96系列8098单片机［1，2］(也可选用兼容的80C196单片机)和5VASZZ系列DSC模块，以软件方法产生阶跃、等速、周期等速和正弦等信号，通过8255直接16位数字输出，或分精粗各12位数字量分送两个DSC转化为三相模拟电压双通道输出。在此过程中，利用8279显示和控制正弦机的运行状态。8098数字正弦机的硬件组成框图如图1。 ……<br/><br/>……]]></description>
