Issues in Multirate Process Control

Multirate systems are encountered when some signals of interest are sampled at a di erent rate than others. For example, in the process industry, composition measurements in distillation columns are typically sampled at a slower rate than temperatures and ow rates. In the context of closed-loop control, such multirate systems pose a challenging problem due to several reasons such as increased c...

Control Issues of Insertion Devices

Insertion devices play crucial roles in new generation light source. Magnetic performance is the most important consideration factor during the design and construction phase. However, control performance is also an important issue from operation point of view. Motion control performance, residual filed compensation scheme and control response time for continue change in gap or phase during ener...

Control Issues in Anaphor Resolution

Much research in computational linguistics has concentrated on treating the individual phenomena of natural language rather than on how these treatments can be made to work together. This paper discusses four respects in which processes embodying individual treatments must be made to cooperate with one another if anaphoric expressions are to be interpreted correctly. These are the coordination ...

Issues in Distributed Control Foratm

Asynchronous Transfer Mode (ATM) network technology is expected to become a central part of the emerging global information infrastructure. ATM networks introduce a number of features that distinguish them from earlier technologies and introduce new issues in network control. This paper ooers a framework for precisely deening and analyzing alternative approaches to the distributed control of AT...
