Adaptive Controllers are susceptible to many commonly occurring implementation problems, and require some form of supervision to maintain good performance. In this thesis a two level adaptive control strategy is presented that uses an expert system to diagnose and correct problems with an adaptive controller. In contrast with other expert supervised adaptive control schemes, where problem treat...

In today’s competitive world, manufacturers have realized that they need to embrace automation as their mantra to success. However, the impact of automation primarily concerns with the effectiveness of process monitoring and control systems. There is a need for a closed loop supervisory system, which integrates and coordinates individual process modules for real-time adjustment, conflict resolu...

background communication skills of operational managers such as head nurses greatly influence the performance of nursing personnel and by extension, the quality of the care provided by them. objectives this study was conducted to identify the role of a development program on communication skills and job satisfaction in head nurses. materials and methods this research was a non-randomized two-gr...

This paper focuses on issues related to implementing timed discrete-event systems (TDES) supervisors, and the concurrency and timing delay issues involved. In particular, we examine issues related to implementing TDES as sampled-data (SD) controllers. An SD controller is driven by a periodic clock and sees the system as a series of inputs and outputs. On each clock edge (tick event), it samples...

Cyber Physical Systems (CPS) often have continuous components interconnected with systems described by discrete state space. Examples of such discrete components may be supervisory controllers or components implemented in software. To design large scale CPS in a compositional manner it would be useful to define a notion of passivity for these discrete components as well. As a first step towards...
