We compare the performance of two distributed nonlinear estimators for a multivehicle flocking system using range measurements only. The estimators are the Distributed Extended Kalman Filter (DEKF) and the Markov Chain Distributed Particle Filter (MCDPF), where the distributed implementation in both cases is done using consensus-type algorithms. The performance of the estimators is compared as ...

This paper presents a study to estimate the composition of an electric load, i.e. to determine the amount of each load class by the direct measurements of the total electric current waveform from instrument reading. Kalman filter algorithm is applied to estimate the electric load composition on a consumer side of a distributed power system. The electric load supplied from the different voltage ...

This paper presents two recursive schemes for current reference generation for shunt active filters under unknown fundamental frequency. The schemes are based on the liner Kalman filter that needs the knowledge of the fundamental frequency. In practice, the fundamental frequency of the power system grid can vary. If it differs from the fundamental frequency considered in the mathematical model ...

This paper deals with the problem of distributed H∞ consensus filtering for a continuous-time Itô-type stochastic system with Wiener process disturbances and Markovian coupling intercommunication delays. The problem is solved based on distributed H∞ filters in combination with consensus strategies. The set of filter nodes form a communication network whose topology is modeled by a directed grap...

this paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. the power filter integrates a passive power filter which is a rl low-pass filter placed in series with the load, and an active power filter which comprises an rl in series with an igbt based voltage source converter. the filter is assumed...

this paper presents a novel method to calculate the reference source current and the referencecompensating current for shunt active power filters (sapfs). this method first calculates theamplitude and phase of the fundamental load current from a recursive algebraic approach blockbefore calculating the displacement power factor. next, the amplitude of the reference mains currentis computed with ...
