Fault tolerant control with respect to actuator failures Application to steam generator process
نویسندگان
چکیده
This paper deals with the analysis of nonlinear reachability and fault tolerant properties of multiactuator nonlinear systems. In this case, the process is a steam generator process containing a set of actuators. After occurrence of one or several actuator faults detected and isolated by Fault Detection and Isolation (FDI) approaches, a quantitative analysis of the faulty system properties helps us to determine whether the faulty system can go on operating or not. Nonlinear reachability analysis that has been presented in this paper allows us to determine the minimal number of actuators that are necessary to keep the system under control.

Fault-tolerant Control for Constrained Linear Systems Based on Mpc and Fdi
This paper considers fault-tolerant control (FTC) for constrained linear systems subject to partial actuator failures. An active fault-tolerant control scheme based on model predictive control (MPC) and fault detection and isolation (FDI) is proposed. The FDI module using a two-stage Kalman filtering algorithm provides simultaneous control parameter and state estimation, which are used to modif...
متن کاملAdaptive Fault-Tolerant Control for Time-Delay Nonlinear Systems with Stochastic Actuator Failures
In [18], a class of nonlinear systems with stochastic actuator failures have been studied. Stochastic functions related to Markovian variables have been introduced to describe the failure scaling factors for each actuators. In this paper we consider the kind of systems involving state-delay, which is much more practical, and adaptive fault-tolerant control problem has been studied. Two main cha...

Boiler-turbines are one of the most important parts in power generation plants. The safety problem in such systems has always been a special concern. This paper discusses the application of control reconfig uration by fault-hiding approach for a boiler-turbine unit. In Fault-hiding approach, after occurrence of a fault, nominal controller of the system remains unchanged; instead, a reconfigurat...

متن کاملDecentralized Adaptive Fault-Tolerant Control for Complex Systems with Actuator Faults
In this paper, an adaptive fault-tolerant control scheme is extended to large-scale interconnected systems with actuator failures and external disturbances. Based on Lyapunov stability theory, a state feedback decentralized controller is designed to compensate for the fault and the disturbance effects, using the overlapping decomposition method. Applying the inclusion principle, the interconnec...
