摘要
用Matlab对Colpitts混沌振荡电路进行模拟和分析.随着开环增益的增大,系统逐渐从周期态进入混沌态,而且吸引子只是单涡卷折叠吸引子.参照混沌吸引子的性质,对电路中三极管的功率和其他元件的功率进行了模拟分析,并计算平均值,证实了三极管的平均功率为负值,其绝对值小于1 W,并且与电路中其他元件功率总和大小相等,符号相反.
The Colpitts chaotic oscillator was simulated and analyzed by using Matlab .With the increase of the open loop gain ,the system changed gradually from periodic state into chaotic state , and the attractor was single vortex folding .The power consumption of transistor and other elements were simulated according to the characteristics of chaotic attractor and their average values were ob‐tained .The experimental results indicated that the average power of transistor was negative and less than 1 W .The sign was on the contrary to the total value of other components .
