In this paper a novel hybrid algorithm for harmonics estimation in power systems is proposed. The estimation of the harmonic components is a nonlinear problem due to the nonlinearity of phase of sinusoids in distorted waveforms. Most researchers implemented nonlinear methods to extract the harmonic parameters. However, nonlinear methods for amplitude estimation increase time of convergence. Hen...

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 sensor fa...

An optimization spiking neural P system (OSNPS) provides a novel way to directly use a P system to solve optimization problems. This paper discusses the practical application of OSNPS for the first time and uses it to solve the power system fault section estimation problem formulated by an optimization problem. When the status information of protective relays and circuit breakers read from a su...

OPTIMAL THRUSTER SELECTION WITH ROBUST ESTIMATION FOR FORMATION FLYING APPLICATIONS By Trent Yang Submitted to the Department of Aeronautics and Astronautics on May 21, 2003 in Partial Fulfillment of the Requirements for the Degree of Master of Science in Aeronautics and Astronautics The research goal was to develop a computationally fast mapper that can be easily configured to any spacecraft w...

Complex systems can significantly benefit from condition monitoring and diagnosis to optimize operational availability and safety. However, for most complex systems, multi-fault diagnosis is a challenging issue, as fault-related components are often too close in the frequency domain to be easily identified. In this paper, the interpolated discrete Fourier transform (IpDFT) with maximum sidelobe...

We present a fast parallel simulator to evaluate the impact of different error control methods on the performance of networks-on-chip (NoCs). The simulator, implemented with message passing interface (MPI) language to exploit multiprocessor server environments, models characteristics of intellectual property (IP) cores, network interfaces (NIs), and routers. Moreover, different error control sc...

The areas of analog circuit fault simulation and test generation have not witnessed the same degree of success as their digital counterparts. This is due mainly fo the complexity of analog behavior and the lack of a fault model. We present a new Jicnctional fault modeling technique called the perturbation fault model. The perturbation fault model is based on an estimation of the distance betwee...

This paper presents a novel fault location method for series compensated transmission lines. It is established based on synchronized voltages sampling and Thevenin impedance from both ends of series compensated transmission line. The method is based on the use of phasor measurement units (PMU) technology which is aimed to be independent of current measurements, fault type, fault resistance, fau...
