fan suction meaning in Chinese
风机负压
Examples
- The above circumstances will create some difficulties for the design of a discharge header pressure of coke oven control system , whose difficulties make it hard to realize an accurate control . in this paper , after comparing the difference of some kinds of decoupling control method , aiming at the feature of the coke oven pressure system and based on the coupling phenomena caused by the fluctuate between border upon channels , using the theory of feedforward and thinking about the influence between the fan suction and the discharge header pressure , a kind method of fuzzy feedforward is presented and used to control the discharge header pressure
本文在比较了目前各种解耦方法的优缺点后，针对集气管压力控制的特点，基于相邻通道的波动引起的耦合现象，采用前馈补偿原则，同时考虑鼓风机吸力对集气管压力的影响，将常规pid控制技术、多变量经典控制技术和多变量模糊控制技术相结合，提出了一种基于模糊逻辑的模糊前馈解耦方法，用于集气管压力控制。 - A coke oven represents a kind of controlled object with a full spectrum of closely coupled factors , such as distributed parameters , no - linearity , time - dependent change and multi - variable features . among them , the discharge header pressure and fan suction are key parameters , and also constitute strongly coupled variables with very close inter - relation , which are fulfilled by the way of regulating coal - feeding and the rate of primary air supply in practice
焦炉是一个分布参数，非线性、时变、多变量紧密耦合的被控对象，其中集气管压力和鼓风机吸力既是关键参数，又是具有紧密关系的强耦合变量，它们均是通过调节给煤量和一次送风量来实现控制的。
