查询词典 closed system

In order to ensure the consistency of the closed-loop system performances, before the AFC is applied, a supervisory controller is used to drive initial tracking errors to a preset closed area, and then the AFC can drive the tracking errors of the closed-loop system to pre-specified neighborhood in the presence of unknown approximation errors of the fuzzy logic system.

为保证系统性能的一致性，在启动自适应模糊控制器前，采用监督控制将初始跟踪误差镇定到给定范围。自适应模糊控制器可在存在模糊逻辑系统逼近误差的情况下，使系统跟踪误差小于预先给定的任意常数。

Simulation results show that the performance of the open-loop control system is poor when the model parameters change. The second system is designed via feedback linearization method. Since the path signal is introduced as feedback signal, the designed closed-loop control system improves the system robustness to the parameter perturbation. Simulation results verify that the closed-loop control system shows better performance than the time optimal control system.

前者侧重于时间最短的控制性能，但由于是开环控制，当出现参数摄动时，系统的性能会受到较大影响；后者由于引入了飞艇轨迹的反馈信号，因而相对提高了系统对参数摄动的鲁棒性，计算量较小，并且仿真结果证实了这种闭环系统设计方案可以抑制参数摄动带来的影响，与时间最优开环控制系统相比，显著提高了控制精度、改善了控制效果。

A new type cement commonly apply closed-circuit circulatory system, that cement production not only rely on closed-circuit grinding system as well as the election system to elect the cement powder, but also the dust collection system to close down.

新型水泥制备普遍采用闭路循环系统，闭路水泥生产不仅要靠粉磨系统把水泥磨出来，靠选粉系统把水泥选出来，还要靠收尘系统把水泥收下来。

There were a great deal of kinds of the grass with high quality and quantity fed to fish To determine the best symbiosis ecosystem of fish and grass on a closed system circulated yearly, several cold and warm grass was selected to analyse the adaptability and nutrition absorbed. It indicted that Lolium multiform Lam. and lemarthria compressa were the best option due to high adaptability of wetness, high coarse protein, fat and fibre and so on in the leaf, high biomass, high bio-filtration effect of N and P, adaption to the low or high temperature, resist to the plant diseases and insect pests, and the food of fish whose forage was grass.

鱼用优质高产牧草的种类繁多，为确定最佳的鱼草共生周年循环系统，本文选择几种冷季牧草和暖季牧草进行生长适应性与营养吸收研究，分析表明，多花黑麦草和扁穗牛鞭草是最佳的冷季牧草和暖季牧草，它们耐水性强，叶片中所含的粗蛋白、粗脂肪、粗纤维等化学成分高，植株的生物量也高，生物过滤养殖废水中的氮和磷效果好，而且可以适应外界环境的低温或高温，抵抗病虫侵害，同时为草食性鱼类喜欢食用。
