Reconfiguration-Based Fault Tolerant Control of Dynamical Systems: A Control Reallocation Approach

Fault-Tolerant Control of a Nonlinear Process with Input Constraints

A Fault-Tolerant Control (FTC) methodology has been presented for nonlinear processes being imposed by control input constraints. The proposed methodology uses a combination of Feedback Linearization and Model Predictive Control (FLMPC) schemes. The resulting constraints in the transformed process will be dependent on the actual evolving states, making their incorporation in the de...

Fault-Tolerant Control for LPV systems based on Fault Compensator

This paper proposes a fault-tolerant control (FTC) scheme for polytopic linear parameter varying (LPV) systems. We first propose a fault compensator whose structure is simple, but effective against actuator faults. Then, in order to show its basic idea, we consider a state feedback FTC scheme based on the fault compensator. Next, the FTC algorithm is extended to output feedback FTC scheme. The ...

553g Fault-Tolerant Process Control: Nonlinear Fdi and Reconfiguration

Charles McFall, Adiwinata Gani, Prashant Mhaskar, Panagiotis D. Christofides, and James F. Davis Chemical plants are large-scale systems that involve a complex, distributed arrangement of a number of processing units (reactors, distillation columns, absorbers, pumps, heat exchangers, etc.) connected in series or in parallel, with recycle of material and energy integration among various parts of...

An Approach to Manage Reconfiguration in Fault- Tolerant Distributed Systems

This paper deals with dynamic resource management for real–time dependability–critical distributed systems. Requirements for such kind of systems span many domains such as time, survivability, and scalability and point out formidable challenges in terms of their fulfillment. An architecture is proposed, based on the agent distributed infrastructure Lira, and enriched with statistical models for...
