Abstract

In this work the existing relations between the imprecise computation and the fault tolerant control (FTC) are analyzed. From those relations, there are constructed FTC systems according to the model of imprecise computation. The found relations establish that the obligatory tasks in the model of imprecise computation correspond with the mission of maintaining the stability of the systems under FTC according to the redundancy degree that assure the structural properties of the systems. On the other hand, the optional tasks in imprecise computation correspond to performance criteria of the systems under FTC are satisfied, which can be degraded under adverse conditions of operation of the system. These correspondences are probed in an example.
