A New Decentralized Fault Tolerant Control Strategy and the Fault Accomodation of Coupled Drives
نویسندگان
چکیده
This paper presented a novel decentralized fault tolerant control strategy for the control of linear multivariable processes. The multiple model based fault tolerant method is used to improve system performance (under model uncertainty and slow variation) and implement active fault tolerant control. In the mean time, we extended the decentralized unconditional stable control to multiple model cases to implement passive fault (partial failure of actuator or sensor) tolerant control under partially isolated failures. This strategy was applied in the fault accommodation of coupled drives. Keywords-component; Fault tolerant control; Unconditional stability; Coupled drives; Multiple model based control;

A New Fault Tolerant Nonlinear Model Predictive Controller Incorporating an UKF-Based Centralized Measurement Fusion Scheme
A new Fault Tolerant Controller (FTC) has been presented in this research by integrating a Fault Detection and Diagnosis (FDD) mechanism in a nonlinear model predictive controller framework. The proposed FDD utilizes a Multi-Sensor Data Fusion (MSDF) methodology to enhance its reliability and estimation accuracy. An augmented state-vector model is developed to incorporate the occurred senso...

In this paper we have presented a new design of fault tolerant comparator with a fault free hot spare. The aim of this design is to achieve a low overhead of time and area in fault tolerant comparators. We have used hot standby technique to normal operation of the system without interrupting and dynamic recovery method in fault detection and correction. The circuit is divided to smaller modules...
متن کاملDesign of an Active Approach for Detection, Estimation and Short-Circuit Stator Fault Tolerant Control in Induction Motors
Three phase induction motors have many applications in industries. Consequently, detecting and estimating the fault and compensate it in a way that the faulty induction motor satisfies the predefined goals are important issues. One of the most common faults in induction motors is the short circuit of the stator winding. In this paper, an active fault-tolerant control system is designed and pres...

This paper introduces a new method to track the saliency of a PMSM motor fed by a four-leg inverter in case of a single phase open circuit fault through measuring the dynamic current response of the motor line currents due the IGBT switching actions. In the case of a single phase open circuit fault, a fault-tolerant control strategy that includes taking appropriate actions to control the two re...
