查询词典 pi

Clinical manifestations are soreness on epigastric region, decreased appetite, distention after meal and eructation. It belongs to "epigastric pain" and "Stomach Pi syndrome" in TCM with characteristics of repetition and pertinacity. In 1978, WHO listed chronic atrophic gastritis as precancerous lesions of gastric cancer because its complications of intestinal metaplasia and dysplasia are closely related to gastric cancer. This has been a research focus in clinical practice and pathology for years.

临床主要表现为上腹隐痛、食欲减退、食后饱胀、嗳气等，属中医学"胃脘痛"、"胃痞"等范畴，具有反覆发作、迁延难愈的特性。1978年WHO将慢性萎缩性胃炎列为胃癌的癌前状态，而在其基础上伴发的肠上皮化生(Intestinal metaplasia，IM)和域异型增生(DYSplasia， DYS)，则与胃癌的发生关系密切，被视为癌前病变(Precacerous lesions Of gastric cancer， PLGC)多年来始终是临床及病理学研究的重点。

The problem of stabilizing networked PI control systems with fuzzy logic compensation is studied by applying the extension of the Hermite-Biehler theorem to the quasi-polynomial stability problem.

该方法的优点是可利用现有的确定性系统的设计方法设计控制器，缺点是由于缓冲区将时滞都转化成最大时滞，降低了系统应有

0引言模糊控制是以模糊集合论、模糊语言变量及模糊逻辑推理为基础的计算机智能控制。它不要求知道被控对象的精确数学模型，只需要提供现场操作人员的经验知识及操作数据。

PI arithmetic is utilized in fuzzy controller to adjust the proportionality factor of fuzzy controller automatically.

模糊控制器与工业过程控制中常用的PID控制器相比具有一定的优点，而它的一个最大缺点就是精度不太高。

The simulation on a system of boiler drum water level control indicates that the fuzzy controller of self-tuning proportionality factor based on PI arithmetic can improve the performance of fuzzy control system and can control the fallacious water level.

为减小模糊控制器的误差，最常用的就是将PID控制与模糊控制结合起来，从而构成模糊PID控制。然而由于引入了积分作用，使得控制过程的响应时间大大增长，失去了模糊控制响应快速的特点。
