feed forward control meaning in Chinese
前馈控制
Examples
- The discussion of feed forward control of military equipment information resource management for equipment technology progress
适于装备技术进步的装备信息资源管理前馈控制探讨 - The nonlinear pid ca n ' t fit the change of the reaction . the feed forward control base on model also ca n ' t fit the change of ph value and flux of the original water . so the control method ca n ' t get a good result
Pid控制算法也无法对反应的变化过程做快速的、精确的反应，在控制过程中很容易引起振荡现象，很难对系统实现最优控制。 - Fuzzy control fit the control of nonlinear , time lag system . it especially fits the control of neutralization process . so fuzzy control is employed in the control system as a feed forward control
模糊控制完全是在操作人员控制经验的基础上实现对系统的控制，无需建立数学模型，具有较强的鲁棒性，适用于非线性、时变、时滞系统的控制，对中和过程的控制尤其适合。 - The automation of coal flotation has been wandering for many years in china . the production efficiency is relatively low because of the feed forward control which adds the flotation reagent based on the fine coal in feed slurry , ignoring the quantity and quality of the products . aiming at this problem , method of measuring the flotation technical parameters was studied , the slurry level meter and the slurry ash - measuring device were worked out , and the computer control system of the coal flotation was designed . the feedback control was realized by using the fuzzy logic control control technology to regulate the reagent addition and the slurry level in the flotation tank according to the concentrate ash content detectedby the coal slurry ash - measuring device developed . the industrial experiment indicates that the performance inedxes of the coal slurry ashmeasuring device have come up to the advanced levek of the world . the application of the detection and control system in huaibei coal preparation plant results in a high concentrate recovery , a decrease of the reagent consumption , ensuring a highly efficient operation
浮选自动化在我国多年来徘徊不前，一直采用根据入浮煤浆中的干煤泥量来确定加药量的前馈控制方法，而不直接以产品的数质量指标作为控制目标，导致浮选生产效率较低.针对上述问题，研究了浮选工艺参数的检测方法，开发了浮选浆位仪和煤浆测灰仪，设计了浮选计算机控制系统，它根据煤浆测灰仪旁线检测的精煤灰分，运用模糊控制技术，通过调整浮选药剂添加量和浮选机浆位，来实现浮选过程的反馈控制.工业性试验表明，煤浆测灰仪的性能指标接近国外先进水平.煤泥浮选测控系统在淮北选煤厂的现场使用，使浮选生产在精煤灰分合格的前提下，得到了较高的产率，并降低了药剂用量，从而保证选煤厂高效率地运行 - Feed back control base on nonlinear pid with self - adjust parameter and feed forward control base on experience model are employed in the practical application . the realization of this control system and its result are introduced in this paper . because the process of the reaction is complicated , it ' s difficult to model for it
在对中和过程自动控制算法的探索中，采用了非线性参数自整定控制和基于模型的前馈控制，本文介绍了这种控制系统的实现和现场控制效果，由于中和控制过程的模型极其难以确定，反应过程变化复杂，因此基于模型的前馈控制无法对ph值和流量值的波动进行有效的补偿。
