一种新方案的提出 在某些场合,人们希望以油品质量指标做为目标函数实现自动控制。但是,目前大多数的在线质量仪表在生产中仅起开环监测的作用。其原因是多方面的,如炼油生产方案,所提要求仅是以提高效率为主,不过分追究产品质量等等。然而,一旦工艺提出直接控制油品质量要求时,用常规控制手段却很难达到预期目的。因为,质量控制系统以在线质量分析仪表做为测量变送单元。而目前这种仪表大都需要很长的、内径很细的采样管线。因而,形成十分
Proposed a new program In some occasions, people want to oil quality indicators as an objective function to achieve automatic control. However, most current online mass meters only function as open loop monitoring during production. The reasons are many, such as oil refining program, the request is only to improve efficiency, but not enough to pursue product quality and so on. However, once the process has been proposed to directly control the quality of oil products, it is difficult to achieve the intended purpose by conventional control measures. Because, quality control system with online quality analyzer as a measurement transmitter unit. At present, most of these instruments need a very long, very small diameter sampling pipeline. Therefore, the formation of very
