Fault Tolerant-Reconfigurable Control for a Mass-Spring System

摘要

The paper presents a novel fault tolerant-reconfigurable control (FTRC) scheme based on condition monitoring and fault diagnosis (CMFD) for inherent dynamic change and anticipated faults of a mass-spring system. The strategy of the FTRC is thatthe four pre-designed controllers are switched according to the results of CMFD and reconfigurable logic. Simulations demonstrate that the control scheme can effectively and rapidly accommodate the inherent dynamic alternation and the break of spring inthe plant, and the controlled system is stable and has a good tracking performance of position and velocity.
