　控制回路性能评估的方法被方法应用于炼油、石化和其他化工领域，在造纸过程中也可以见到一些应用的案例。基于Zui小方差的性能评估技术已经成熟，并已成为日常生产中使用的标准方法。市场上已有一些控制回路性能评估与监视软件。

　　Honeywell的Loop Scout作为一款全面的回路工作流管理软件，包括了回路分析功能、阀门诊断功能、以强大控制理论为基础的调节功能以及针对PID控制器的选择性技术。该软件能够收集流水线中过程量、节点、控制器输出以及控制回路组态方面的数据，然后产生各条回路的性能报告。专业级的指导工具会引导新用户解读这些数据，并且提供额外的测试用来确定是维护方面存在问题、调节方面存在问题还是控制方案自身就有问题。

　　Rockwell的RSLoop Optimize专门用来对Allen-Bradley PLC-5、SLC 500以及Logix控制器中的PID回路作分析和调节，可以起到提高流程的稳定性、提高产量和Zui大化生产效率的目的。

　　ABB的Optimize IT Loop Performance Manager帮助控制工程师和流水线操作人员在ABB及其竞争对手的系统中，对控制回路进行启动、诊断、维护等操作。

　　B&R的Automation Studio通过自动设置所有闭环控制参数来实现更为快捷的温度控制回路的调试。该软件利用选择库功能块来处理闭环温度控制，直观的用户界面允许使用者轻松选择温度范围和温度传感器的类型，并且定义温区需求，无需额外的程序就可实现温度控制回路的优化处理。

　　目前，市场上关于控制回路性能评估的软件商品种类繁多。这些回路状态监控、诊断工具都能够提供自动和手动调整、分析回路的功能；监控生产线上的每条回路，而且不区分平台或制造厂商；执行非干扰式、持续式的在线性能分析；提供专门的回路状态指标，例如误差分布、误差、过程变量积分以及经济性影响；将回路状态报告发送到工厂的每个商业层，并通过网络传播出去。不管是受益于回路优化技术的改进还是其他的原因，在过程工业中，控制回路性能确实得到了提升。
