Supervisory Distributed Computer Control Systems

چکیده
Supervisory Distributed Computer Control Systems help the operator to run the process by putting control and monitoring functionality at his or her disposal. These systems support the Human Machine Interface, Message Handling, Archiving, Hardware Diagnostics and they execute control functions automatically. With respect to these requirements, the functionality of supervisory distributed control systems has remained nearly unchanged in the last two decades. In contrast, the structure of the underlying communication and computing systems changed dramatically, driven by the revolution in Internet and PC technology. This section illustrates the principle functional requirements and presents a brief introduction to modern system configuration concepts.

Partial Observation in Distributed Supervisory Control of Discrete-Event Systems
Distributed supervisory control is a method to synthesize local controllers in discrete-eventsystems with a systematic observation of the plant. Some works were reported on extending this methodby which local controllers are constructed so that observation properties are preserved from monolithic todistributed supervisory control, in an up-down approach. In this paper, we find circumstances in ...

متن کاملStability Analysis of Networked Hybrid Systems
Hybrid dynamic systems are of major research interest nowadays due to their use as models in many applications in computer science and systems control. One of the major problems in hybrid dynamic systems is establishing their key property of stability, which also is important in controller design. The use of communication networks in supervisory control of distributed control systems introduces...
متن کاملEnhancement of Robust Tracking Performance via Switching Supervisory Adaptive Control
When the process is highly uncertain, even linear minimum phase systems must sacrifice desirable feedback control benefits to avoid an excessive ‘cost of feedback’, while preserving the robust stability. In this paper, the problem of supervisory based switching Quantitative Feedback Theory (QFT) control is proposed for the control of highly uncertain plants. According to this strategy, the unce...
