简介:纸建议调查二的同步的一条分析途径在空间运动的一个颤动的系统联合了exciters。为二exciters的平均尖速度介绍骚乱参数,我们推出二exciters,联合矩阵的惯性在是对称的尖速度的非维的联合方程并且联合矩阵的僵硬在一个非反响的颤动系统是反对称的。阶段角度的联合余弦效果将引起对二台马达起作用限制二exciters之间的阶段差别的增加以及在跑期间支撑它二exciters的对称的转矩的动态典型表演处理的联合的分析。它身体上解释二exciters的自我同步的怪癖。颤动的阶段角度的余弦效果由每exciter愿望减少使它惯性的时刻激动。每exciter的惯性的剩余时刻代表它惯性的相对时刻。exciters是二exciters的惯性的相对非维的时刻都比乘他们的产品的零和四伟大的二的同步的稳定性条件比他们阶段角度的联合余弦效果的系数的平方大,它等价于联合矩阵的惯性是积极的明确并且所有它的元素是积极的。数字结果证明颤动的系统的结构能保证同步操作的稳定性条件。关键词频率俘获-稳定性-同步-颤动的系统-振动同步传播工程被辽宁省学院科学和研究(2008S095)支持,中国的国家自然科学基础的关键工程(50535010,50805020)并且中国(2007AA04Z442)的高技术研究和开发节目。
