Distributed locating algorithm MDS-MAP (LF) based on low-frequency signal

The positioning error of distributed MDS-MAP algorithms comes from two aspects: the local positioning error and the position fusion error. In an attempt to improve the positioning result in both local positioning accuracy and global convergence probability, this paper proposes a novel MDS-MAP(LF) algorithm, which uses low frequency signal to measure the inter-sensor distance rather than shortes...

A New Fuzzy Stabilizer Based on Online Learning Algorithm for Damping of Low-Frequency Oscillations

A multi objective Honey Bee Mating Optimization (HBMO) designed by online learning mechanism is proposed in this paper to optimize the double Fuzzy-Lead-Lag (FLL) stabilizer parameters in order to improve low-frequency oscillations in a multi machine power system. The proposed double FLL stabilizer consists of a low pass filter and two fuzzy logic controllers whose parameters can be set by the ...

Micro-Doppler Signal Time-Frequency Algorithm Based on STFRFT

This paper proposes a time-frequency algorithm based on short-time fractional order Fourier transformation (STFRFT) for identification of a complicated movement targets. This algorithm, consisting of a STFRFT order-changing and quick selection method, is effective in reducing the computation load. A multi-order STFRFT time-frequency algorithm is also developed that makes use of the time-frequen...

RFID in Metal Environments: An Overview on Low (LF) and Ultra-Low (ULF) Frequency Systems

Depending on their frequency, radio waves can be absorbed by water and biological tissues (Bottomley & Andrew, 1978). They can also be shielded by metals due to the eddy currents. These effects constitute a huge problem for the implementation of radio frequency identification (RFID) systems in real environments. RFID systems can be classified into three different groups depending on the physics...
