摘要
研究了永磁同步电机的稳定条件和发生混沌的机理,并根据分析找出了从电机本体方面避免产生混沌的策略。首先采用将电机模型系统分解成若干线性子系统,其相互连接却又是非线性的方法来对系统进行了分析,讨论了系统稳定的条件。其次指出了用最小能量法控制混沌和混沌反控制策略。最后给出了参数变化时电机所经历的不同阶段以及发生混沌和稳定时电机参数的边界曲线。
The stable condition and the occurrence mechanism of the chaos of the permanent magnet synchronous motors are presented. The strategy from the motor itself to prevent the chaotic phenomenon is given. The model system is decomposed to some linear subsystems, but the mutual connection of these subsystems are nonlinear. The stable conditions of the system and the strategy of the minimum energy that used to control chaos and chaos anti-control is discussed. When the parameters of motor changed, the phase locus of the system experiences three different stages, Simulator maps the stable and the chaos boundary curve of the system when the parameters of the motor varying,
