Summary
This study introduces a novel framework for reconfiguring discrete event system (DES) controllers with dynamic observation sets. The new approach enhances controller tolerance by dynamically adjusting states and feedback functions.
Area of Science:
- Control Theory
- Computer Science
- Systems Engineering
Background:
- Discrete Event Systems (DES) controllers often face challenges with dynamic event observation sets.
- Existing reconfiguration methods may lack adaptability and tolerance to changing system dynamics.
Purpose of the Study:
- To develop a robust framework for reconfiguring DES controllers with dynamic observation sets.
- To design a mega-controller capable of monitoring and adapting DES controller states and observation sets.
- To improve controller tolerance compared to prior methods.
Main Methods:
- A framework for controller reconfiguration is developed.
- A mega-controller is designed to continuously monitor the DES controller's observation set and state.
- Controller states are aggregated or disaggregated upon changes in the observation set.
- Feedback functions are adjusted to resolve control conflicts arising from observation set changes.
Main Results:
- The proposed reconfiguration framework yields a more tolerable controller.
- The mega-controller effectively manages dynamic observation set changes.
- The method demonstrates improved performance over existing approaches [5].
Conclusions:
- The developed framework provides an effective solution for reconfiguring DES controllers with dynamic observation sets.
- The mega-controller architecture ensures adaptability and improved tolerance in control systems.
- This work advances the field of adaptive control for discrete event systems.
