Sensor location for fault accommodation problem

Abstract

The problem of sensor location for fault accommodation problem in nonlinear dynamic systems is considered. Solution of the problem is related to constructing the control law which provides full decoupling with respect to fault effects. The logic-dynamic approach is used to solve the problem. The main features of this approach are: it involves known linear methods that results in possibility to solve the fault accommodation problem by existing programming systems without using the symbolic software and it can be applied both to discrete-time and continuous-time systems. Existing conditions are formulated and calculating relations are given for the control law. Theoretical results are illustrated by example.
