It is need to carry on the compression to the remote sensing image for the speedy transmission and the effective memory remote sensing image. The multi-spectrum remote sensing image has the very strong relevance among spectrums. In multi-wave band image compression, to eliminate the spectrum relevance, both must consider to eliminate the statistical dependence, and to eliminate the structure relevance...
To solve the low efficiency of electric excitation claw-pole synchronous generator (EECSG) and the challenges to regulate the magnetic field of permanent magnet (PM) claw-pole synchronous generator, a novel hybrid excitation claw-pole synchronous generator (HCPSG) with magnetic circuit series connection was proposed in this paper. Through the simulative study to the generator using the calculation...
Rotary eccentric loads often lead to vibration problems in motors, which may reduced their reliability and operating life. In order to reduce the radial vibration in permanent magnet motors, a real time detection method for rotary eccentric load based on the theoretical analysis of the motor vibration and the mechanical analysis was given, and a novel control strategy based on FOC (field oriented...
A novel control method is presented for improving the reliability of transformerless cascade STATCOMs operating under various faults. A modified H bridge circuit is proposed, and it could be totally bypassed under various faults while the STATCOM keep working. During the fault transient, by controlling the phase of a STATCOMpsilas output voltage, the DC capacitors could be charged or discharged to...
A fast and robust method to analyze the transient response of free-running oscillators is proposed. It is based on the harmonic balance technique derived from the warped multi-time partial differential equation approach. We show for the first time how to precisely obtain initial boundary conditions that are consistent with arbitrary physical initial conditions in the system of ordinary differential...
