振动现象
Examples
- The task in the open loop system is to get lpg injection duty ratio in pre - set two dimension map according to practical engine operation condition , while the task in the closed - loop system is to calculate lpg injection duty ratio by the approaching increment method or the proportion and integral ( pi ) controller according to the signal of the oxygen sensor . to eliminate the oscillation phenomena of the signal of the oxygen sensor in low - speed condition , this paper develops the stable increment method
开环阶段根据实时工况参数对事先制取的喷气占空比map图执行取值操作；闭环阶段根据氧传感器反馈信号通过增量逼近法或pi环节计算输出适合即时工况的喷气占空比值；为解决低速振荡现象，本文运用固定增量法，对系统进行低速振荡微调。 - A powerful tool of dynamical system analysis named normal form method is presented in this dissertation , and then it was used to analyze oscillation phenomena in interconnected power grids . using nonlinear coordinate transformation of normal forms , a fully described power system can be converted to an equivalent reduced order model , which can still use the conventional modal analysis of small signal stability problems
论文将动力系统非线性分析的正规形理论应用于互联系统低频振荡分析中，利用正规形方法的非线性坐标变换，将高阶电力系统转化为等价的低阶系统，在保留非线性信息的同时，使其仍然可以使用常规小信号稳定研究的模式分析方法。
