It only needs routine closed-loop operating data and knowledge of the process timedelay using minimum variance as a benchmark in controller performance assessment.
用最小方差准则来评价控制器的性能,仅需过程变量的常规闭环操作数据和过程的时间延迟特性。

Tests showed that the boiler delay response mainly occurred in the powder making process, and was restricted by operating requirements, and this delaytime was difficult to overcome.
试验表明,锅炉延迟响应主要发生在制粉过程,受运行要求限制,该延迟时间难以克服。

The oblique sounding is one of the powerful tools, by which an oblique ionogram is obtained with the group path or timedelay against operating frequency.
