The validity of mathematical model as basis to research the boiler-turbine coordinated control system will direct impact the research result. Based on the energy conversation law, the Bell- Astrom model has deeply analyzed in this paper. The mathematical deducing offer a method applied to analyze and distinguish a mathematical model. Moreover it has provide that the mathematical model much more accord...
A delay-locked loop of multi-band selector with wide-locking range and low power dissipation is presented. The architecture of the proposed delay-locked loop consists of phase frequency detector, charge pump, band selector, multi-control delay line, and start-up circuit. The multi-band selector is used to extend operation frequency of delay-locked loop by switching the multi-control delay line. The...
