First of all, the nonlinear mechanical model of the active-control landing gear system is developed. Then, the PID controller of optimization is designed according to the optimal control theory in the environment of Matlab. Last, the performance of active and passive control landing gears are simulated under the condition that signal of runway is the signal of step in the environment of Simulink....
The transformer is the indispensable important equipment in the power system. Optimization design of transformer has become an urgent requirement. This paper takes the typical voltage transformer JDCF-110 as the research object. Based on the deep study on the structure and the basic design method, the genetic algorithm is applied in the optimization design. Optimization model is determined, optimization...
with English, and they are not suitable for Chinese character synthesis. In this paper, we propose an unified approach for modeling and synthesizing Chinese characters. Using a three-level hierarchical representation, each character is decomposed into basic components, which forms the stroke database and radical database. In the synthesis process, we use a wavelet-based approach to select proper strokes...
