摘要： A controller and loop performance monitoring system is coupled to a controller, detects loop performance degradation in time, and diagnoses a cause of the loop performance degradation. If the cause of loop performance degradation is poor controller tuning, a re-tuning mechanism is triggered. If the cause of loop performance degradation is external to the controller (a disturbance acting on the loop, hardware malfunction etc.), an action defined in control strategy is taken, or the user is informed via alarm, user interface, or upper layer software that collects the performance measures. The monitoring itself is designed to be recursive and with low memory demands, so it can be implemented directly in the controller, without need for data transfer and storage. The monitoring is modular, consisting of oscillation detection and diagnosis part, performance indices part, internal logic part, and triggering part, easily extensible by other performance indices or parts (e.g. for overshoot monitoring). The oscillation detection and diagnosis part includes controller output oscillation monitoring, the performance indices part includes predictability index and offset index. The outputs of the controller and loop performance monitoring are overall loop performance together with loop diagnosis information, and overall controller performance together with controller diagnosis. The outputs of the controller and loop performance monitoring are used as parts of controller and loop performance monitoring user interface.

摘要翻译：控制器和环路性能监控系统耦合到控制器，在时间上检测环路性能下降，并诊断环路性能下降的原因。如果环路性能下降的原因是控制器调谐不良，则会触发重新调谐机制。如果环路性能下降的原因在控制器外部（作用在环路上的干扰，硬件故障等），则采取控制策略中定义的动作，或通过报警，用户界面或上层软件通知用户收集绩效指标。监控本身被设计为递归且具有低内存需求，因此可以直接在控制器中实现，无需数据传输和存储。监控是模块化的，包括振荡检测和诊断部分，性能指标部分，内部逻辑部分和触发部分，可以由其他性能指标或部件（例如过冲监视）轻松扩展。振荡检测和诊断部分包括控制器输出振荡监测，性能指标部分包括可预测指标和偏移指标。控制器和回路性能监控的输出是整体回路性能以及循环诊断信息，以及总体控制器性能以及控制器诊断。控制器和回路性能监控的输出用作控制器和环路性能监控用户界面的一部分。
