【摘要】 转差频率(sf)型矢量控制系统是一种较为实用的矢量控制系统。但由于该系统是磁通开环控制的,因此,系统动、静态性能对参数变化较敏感。本文着力定量分析并验证了参数变化对系统性能的影响,提出了系统中关键性参数 K_s (转差增益)的整定及补偿方法。本文是以电流源型逆变器进行系统试验的。更多还原

【Abstract】 The slip frequency(feedforward)field-oriented control is a practical vector control sys- tem.But its open loop compensation technique makes the dynamic and steady performances parameter sensitive.In this paper,the influence of motor parameter deviations on the performances has been quanti- atively analysed and demonstrated.The tuning procedure and compensation strategy of the significant uning variable Ks(slip gain)have been presented.All tests are performed on current source inverter.更多还原
