When a short-circuit fault occurs in phase, the faulty phase needs to be removed artificially from system because of loss capability generate torque. In this case, both current and phase-loss would additional torque ripples. study, novel fault-tolerant control strategy is introduced achieve low ripple operation five-phase permanent magnet synchronous motors with trapezoidal back electromotive f...

The purpose of this master thesis is to contribute a service-based decentralized architecture for Electronic Control Unit (ECU) with fault tolerant control. As ECU systems are becoming large-scaled, centralized-architecture fault tolerant control is facing challenges in performance, complexity and engineering, for its dependencies, nonmodular, non-scalable and so on. In Scania’s ECUs, the archi...

In this paper, we address fault-tolerant control for non-linear plants. We perform soft fault detection and isolation for partial fault detection. A new method is proposed that combines model predictive controllers with fuzzy Takagi-Sugeno models. An example is presented to illustrate the functionality of the proposed approach. Keywords— Fault detection and isolation, multiple models, fuzzy Tak...

Loss of control accounts for over 25% of aircraft accidents worldwide. This paper presents a fault tolerant flight control strategy for increasing aircraft safety. The work has been undertaken within the Action Group on Fault Tolerant Control (FTC) of the European GARTEUR program, which develops collaborative efforts in Europe to create new FTC technologies that could significantly advance the ...

Scalable Distributed Data Structures (SDDS) can be applied for multicomputers. Multicomputers were developed as a response to market demand for scalable and dependable but not expensive systems. SDDS consists of two components dynamically spread across a multicomputer: records belonging to a file and a mechanism controlling record placement in the file. Methods of making records of the file mor...

Application of formal methods helps us to gain confidence in building correct software. On the other hand, to guarantee dependability of the overall system we need to build fault tolerant software, i.e., software which is not only fault-free but also is able to cope with faults of other system components. Obviously, this goal is attainable only if fault tolerance mechanisms constitute an intrin...

Applying flat systems technique in attitude fault tolerant control of an under-actuated satellite has been investigated in this article. The main purpose of this study is development and implementation of a new idea in order to recovery of satellite stability and its acceptable performance in actuator fault scenarios. Solving the attitude fault tolerant control problem is based on consideration...

Fault-tolerant distributed algorithms are central for building reliable spatially distributed systems. Unfortunately, the lack of a canonical precise framework for fault-tolerant algorithms is an obstacle for both verification and deployment. In this paper, we introduce a new domainspecific framework to capture the behavior of fault-tolerant distributed algorithms in an adequate and precise way...
