【摘要】 本文首先对异步机暂态数学模型进行分析,推导出异步机在转子磁场定向控制时的传递函数,从理论上给出速调采用变结构参数设计的依据,并在实验中得到证实.解决了系统在整个调速范围内的稳定性问题。更多还原

【Abstract】 This paper analysed first IM dynamic mathe matic model,and derive IM transfer function un- der rotor megnatic field orientated.Parameter design foundation was provided on theory for speed regu- lator adopted variable structure and the result was affirmed through experiment.The stability problem was resolved in all adjustable speed region。更多还原
