我们化工动态学及过程控制研究室,自从1978年恢复招收研究生以来,先后招收了16名硕士和1名博士研究生,其中5名已获得硕士学位,今年计划招收硕士生9名、博士生2名。通过几年来的实践,我们深深感到在研究生的培养教育中,目标是培养又红又专的高级科技人才,重点是培养他们发现问题、观察问题、分析问题和处理问题的能力,学位论文阶段则是培养这种能力的最好环节。在学位论文工作中,我们感到指导教师必须充分发挥主导作用,要根据国内外学科发展的趋势,考虑研究生本人的基础和特长,结合科学研究的总体计划,选择好研究生的论文题目。研究课题应尽可能联系生产实际,使论文具有一定的实用价值。在解决实际生产问题时,必须应用先进的技术手段和设计方法,使论文具有一定的独创性。与此同时,要善于应用自动控制理论等知识, 相似文献

INTRODUCTION Traditionally, in real-time schedule theory,real-time requirements are classified into two types,hard real-time (HRT) and soft real-time (SRT)(Giorgio, 1997). HRT requirement is mainly util-ized in temporal safety-critical applications on thetemporal aspect of processing a task. For applica-tions with HRT requirement, such as process con-trol or manufacture automation, deadline miss isnot tolerated, i.e., each task of an HRT applicationmust meet its deadline, and ot… 相似文献

(m,k)-firm real-time or weakly hard real-time(WHRT)guarantee is becoming attractive as it closes the gap between hard and soft(or probabilistic)real-time guarantee,and enables finer granularity of real-time QoS through adjusting m and k.For multiple streams with(m,k)-firm constraint sharing a single server,an on-line priority assignment policy based on the most recent k-length history of each stream called distance based priority(DBP)has been proposed to assign priority.In case of priority equality among these head-of-queue instances,Earliest Deadline First(EDF)is used.Under the context of WHRT schedule theory,DBP is the most popular,gets much attention and has many applications due to its straightforward priority assignment policy and easy implementation.However,DBP combined with EDF cannot always provide good performance,mainly because the initial DBP does not underline the rich information on deadline met/missed distribution,specially streams in various failure states which will travel different distances to restore success states.Considering how to effectively restore the success state of each individual stream from a failure state,an integrated DBP utilizing deadline met/missed distribution is proposed in this paper.Simulation results validated the performance improvement of this proposal. 相似文献

This paper presents a new design of robust optimal controller for multivariable system. The row characteristic functions of a linear multivariable system and dynamic decoupling of its equivalent system, were applied to change the transfer function matrix of a closed-loop system into a normal function matrix, so that robust H∞optimal stability is guaranteed. Furthermore, for the decoupled equivalent control system the l∞optimization approach is used to have the closed-loop system embody optimal time domain indexes. A successful application on a heater control system verified the excellence of the new control scheme. 相似文献
