Wind turbine is a mechanical-electrical—hydraulic integration complex dynamic systems, which consists of the mechanical, electrical and hydraulic servo mechanism, with nonlinear and strong coupling characteristics; Random wind makes the wind turbine shows some characters such as randomness, hybrid and so on. The accidents of the wind turbine become more frequent both at home and abroad; From bearing...
Periodically inserted I-Frames will introduce periodical flickering artifact. For suppressing the flickering, a PI-method is proposed in this paper, in which the GOP length is enlarged and PI-frames are periodically inserted in each GOP. The PI-frames in PI-method are coded as both P-frames and I-frames, namely RP-frames and RI-frames respectively. The RP-frames will be decoded if there is no transmission...
Since there has been a growing demand of DSP-based video coders and most existing rate control methods don't suit them well because of their high time complexity, this paper proposes an improved rate control algorithm to deal with the problem. Based on the analysis of the specialties of those coders, the proposed algorithm includes rate control in three levels: selects the encoding frames, allocates...
