This paper presents the improvement of transient stability of a multi-machine power system with a STATCOM. Transient stability improvement is essential from the view point of maintaining system security that is the incidence of a fault should not lead to tripping of generating unit due to loss of synchronism. Static synchronous compensator is widely used in power system to control power by inje...

Fault-tolerant control methods have been extensively researched over the last 10 years in the context of chemical process control applications, and provide a natural framework for integrating process monitoring and control aspects in a way that not only fault detection and isolation but also control system reconfiguration is achieved in the event of a process or actuator fault. But almost all t...

From low level perspective, fault diagnosis conducted and analyzed to enhance robustness and stability. Composing state equation of interior permanent magnet synchronous motor (IPMSM), current sensor fault and position senso...

In this paper, the controller synthesis problem for fault tolerant control systems (FTCS) with stochastic stability and H2 performance is studied. The system faults of random nature are modeled by a Markov chain. Because the real system fault modes are not directly accessible in the context of FTCS, the controller is reconfigured based on the output of a Fault Detection and Identification (FDI)...

One of the worst types of fault that a power system should be designed to withstand is a short circuit. Within the various types of fault current limiters, the superconducting fault current limiter (SFCL) has an extremely fast current limitation. The rapid switching action and the self-sensing nature of the superconductor make SFCLs particularly attractive in fault protection. This very fast ti...

Rapid developments are occurring in design of electrical machines and its control. To get optimum performance under normal/fault condition needs implementation of fault tolerance. Next decade is of Permanent Magnet Synchronous Machines. The paper presents mathematical modeling of PMSM. A current and speed controller is designed to implement fault tolerance and its stability analysis.

Abstract: This paper considers the problem of fault estimation and accommodation for a class of switched systems with time-varying delay. An adaptive fault estimation algorithm is proposed to estimate the fault, moreover, constant or time-varying fault can be estimated. Meanwhile, a delaydependent criteria is obtained with the purpose of reducing the conservatism of the fault estimation algorit...

Integral Sliding Mode Fault Tolerant Control Schemes with Control Allocation Mirza Tariq Hamayun The key attribute of a Fault Tolerant Control (FTC) system is to maintain overall system stability and acceptable performance in the face of faults and failures within the system. In this thesis new integral sliding mode (ISM) control allocation schemes for FTC are proposed, which have the potential...

Focusing on a class of networked control systems built around wireless sensor networks (WSN), the controller and the actuator in systems are assumed to be time-driven and the clocks are fully synchronized. The observer based on discrete switched systems is designed to detect faults which occur in the system. Firstly, by studying the transmission characteristics of data with wireless sensor netw...
