摘要
在综合分析PMSM系统基础上,通过数值计算Lyapunov指数谱、分岔图等,讨论了永磁同步发电机系统的混沌分岔行为及周期窗口的形态变化;分析计算了系统在二维参数空间的双参数特性。结果显示系统在倍周期分岔中会出现缺边分岔现象,在双参数空间系统出现复杂的分岔结构,两个控制参数对系统动力学行为的影响特性有所差别与影响。
Based on the comprehensive analysis of the basic dynamic characters of PMSM dynamos system, through the calculation of Lyapunov exponent spectra, bifurcation diagrams and so on, the chaotic bifurcation and mutative characteristic thoroughly in the periodic windows of the system was discussed, and the dual-parameter characteristic was also analyzed. It is found that a boundary line is absent in period-doubling bifurcations and a complicated bifurcation structure appears in 2D parameter space, the influences of two control parameters to the dynamic behavior are different.
