在开始PID自整定调整前，整个PID控制回路必须工作在相对稳定的状态。 

　　稳定的PID是指过程变量接近设定值，输出不会不规则的变化，且回路的输出值在控制范围中心附近变化。 

　　问题与解决方法： 

　　1.PID输出总是输出很大的值，并在这一区间内调节变化 

如何获得一个稳定的PID回路 

　　产生原因： 

　　．增益（Gain）值太高 

　　．PID扫描时间（sample time）太长（对于快速响应PID的回路） 

　　解决方法：降低增益（Gain）值并且/或选择短一些的扫描时间 

　　2.过程变量超过设定值很多（超调很大） 

如何获得一个稳定的PID回路 

　　产生原因：积分时间（Integral time)可能太高 

　　解决方法：降低积分时间  

　　3.得到一个非常不稳定的PID 

如何获得一个稳定的PID回路 

　　产生原因： 

　　．如果用了微分，可能是微分参数有问题 

　　．没有微分，可能是增益（Gain）值太高 

　　解决方法： 

　　．调整微分参数到0－1的范围内 

　　．根据回路调节特性将增益值降低，最低可从0.x 开始逐渐增大往上调，直到获得稳定的PID。

STEP7在WINOOWsXP/Server2003中的用户权限

　　请注意下列与用户权限相关的要点：

　　为了可以使用STEP 7，必须至少以用户登录(不是以客人登录)。

　　若要安装STEP 7软件和HSP，使用"设置PG/PC接口"应用程序设置模块和更改设置，要求具备管理员权限。

　　若要使用选项数据包，则检查特定选项数据包要求具备何种权限。

　　如果项目存储在NTFS驱动器上，则用户必须在此具有完全访问权限。这也适用于HSP升级版文件夹(默认路径：C:\HWUPDATES)。默认项目目录STPROJ范围内的访问权自动对所有用户开放。

　　注意

　　仅对STEP 7启用使用用户权限工作。不确保用户权限足以操作选项数据包。此处可能需要管理员权限或超级用户权限。

　　在安装/卸载新硬件后，计算机必须在管理员权限下至少启动一次。

中国石油网消息：大庆石化公司ABS树脂产品掺合PLC控制系统经过半年的投用运行，大小造粒线分离技术日前获得成功。去年7月份，化工三厂在装置停车大检修期间，对ABS树脂产品掺合PLC控制系统实施大小造粒线分离的更新改造，有效地减少了非计划停车，确保了装置长周期运行。 

PLC是工厂自动化控制最重要的控制装置之一，在工厂中拥有广泛的应用。随着技术的进步，PLC已经脱离了“逻辑控制”的简单范围，更多的PLC拥有模数转换、数模转换、高速计数、速度控制、位置控制、轴定位控制、温度控制、PID控制、远程通信和高级语言编程等功能。

由于技术发展的历史原因，传统的PLC产品还是比较封闭的。但在信息相互交流对即时性、流通性要求日益加深的今天，PLC要继续适应工厂控制的需要，开放性趋势已经日趋明显。伴随着PLC的不断开放，其拥有的功能也更加丰富。本期我们将对开放性更高的PLC功能发展进行探讨。

开放趋势已经显现
