基于辅助发生器预测混沌运行状态方法的研究

利用谐波平衡模拟法对电路中的混沌运行状态进行预测,更便于进行电路设计与分析,在高频电路模拟中,可以显示出混沌的同宿分岔轨迹,并预测和计算出这些轨迹的路线.在模拟非线性较强的混沌电路时,会因耗时太多而降低其实用性.通过在谐波平衡模拟法的基础上提出一种基于辅助发生器的新方法,可以克服谐波平衡模拟法存在的不足,对混沌的运行状态有一个精确的预测.在高频电路的设计中,对比上述两种方法,采用辅助发生器可以提高设计效率与准确性,更好的选择电路参数,具有很好的实用性.

A technique for chaos prediction using auxiliary generators

Using harmonic balance simulators can make the work of circuit design and analysis easier to do.When this technique is applied to high frequency circuits,it can exhibit homoclinic bifurcation routes.But when used in simulating nonlinear chaos circuits,its practicability will be undermined as it is too time-consuming.To overcome the shortcomings of harmonic balance simulators,a new method is presented for the detection of chaotic,based on the auxiliary generators(AG's),which can present a precise predictation for chaotic operating status.A comparison of the use of harmonic balance simulator and that of the auxiliary generators(AG's) in high frequency circuits indicates that the use of auxiliary generators can improve design efficiency and veracity as well as practicability.
