Temperature control exists widely in every aspect of social life , and pid is the mainly adopted control algorithm in practice . due to the environment variation pid parameters in - process tuning is not attainable , which negatively effects control quality 传统的控制方法多采用pid控制,但pid的参数不易实现在线调整,特别是用在高精度温度控制时,出于存在外界因素的干扰,严重地影响了控制的品质。
Combined with the engineering practice , the author puts forward the synthetical prevention and cure technique , construction technology and controlling quality measurement , and discusses preventing and curing the jump disease in the bridge abutment of the highway 结合工程实际,提出了高速公路桥头跳车病害综合防治技术、施工工艺及质量控制手段,为今后防治高速公路桥头跳车病害进行了有益的探讨。
Through the field compound welding of the runner of no . 4 generating unit in lianhua hydropower station , a set of the measures and experience of controlling quality have been gained , which can be used in the installation of the generator " s runner in the similar structure for reference 通过对莲花水电站4号机组的转子现场组焊工作,得出了一套控制质量的措施和经验,对同类结构的发电机转子组装有一定的借鉴意义。
It has an advantages of low modek good robustness , strong adaptation and is applicable for the control of digital computer . it may acquire the better control quality if adaptive inverse control based on neural network applies to industrial process control 具有对模型要求低、鲁棒性好、自适应能力强、适用于数字计算机控制昆明理工大学硕士学位论文中英文摘要的优点,将之用于工业过程控制中可以取得较好的控制品质。
Quality is primary and credit is paramount is guideline of cathay , therefore , it made tremendous efforts to control quality and has got a great success : in aug . 1998 , cathay was accredited to iso 9002 - 1994 ; in may 2002 , cathay was accredited to iso9001 - 2000 公司一贯坚持“质量第一,信誉至上”的方针,十分重视质量监控,取得显著效果。于1998年8月通过iso9002 - 1994国际认证2002年5月通过iso9001 - 2000认证,受到客户的好评。
The thesis introduces the basic work flow of the seismic exploration and the importance of the control quality and evaluation work , putts forward the function requirements of the system in details which is the basic of the whole system design 本文从地震勘探原理出发,介绍了地震勘探的基本工作流程,讲述了野外地震资料采集质量监控和评价工作的重要性,并在此基础上提出了《地震资料采集质量监控及评价系统》的详细功能需求。
The company strength is rich , the fixed assets of the factory are 150 million dollars , produce more than 230 staff directly , engineering , and product in charge of personnel 30 over people , company control quality and pass iso9002 international quality authentication to 1999 strictly 公司实力雄厚,工厂固定资产150万美元,直接生产员工230余人,工程技术及品管人员30余人,公司严格控制品质并于1999年通过iso9002国际品质认证。
But , the control and evaluation work for the data quality still have finished by hands till now , always with low efficiency and disturbing . so , it ' s urgent to design a scientific system for the control quality and evaluation with quantitative analysis 然而,目前野外质量监控和评价工作还停滞在手工阶段,工作效率较低而且还存在很大的人为干扰,因此设计和开发一套科学、定量的《地震资料采集质量监控及评价系统》已经成为了质量监控工作的必然需求。
Thus the deficiencies accompanying the traditional self - repairing control law are avoided , which are long repairing time , bad control quality and low repairing ability . consequently , the method becomes a very potential and spirited researching aspect . this article is based on paper [ 33 ] 这样就避免了传统的自修复控制方法所伴随的修复时间长、修复过程控制品质差、修复能力较低等方面的不足,从而成为飞行自修复控制中一个极有前途和生命力的研究方向。
