摘　　要：针对异步电动机启动过程的特点,提出了应用于电动机软启动控制的带加权因子插值模糊控制方法,它既能自适应参数的变化,又能克服输出模糊量变化时控制量的跳变,同时其算法简洁,易于在PLC等一般工业计算机上实现。实践表明,该控制方法具有响应快、超调小、稳态精度高和自适应能力强等特点,完全满足电机软启动要求。This paper puts forward a kind of interpolation fuzzy algorithm with weighting factors applied in induction motor intelligent soft starter according to the characteristics of the induction motor startup process. It is not only able to adapt itself to variable parameters automatically, but also keep the output of control system from changing suddenly when the fuzzy output changes. Its simple calculation is easy to be carried out on ordinary industrial computers. Practice suggests that this control theory presents a rapid response, a small overshoot, a delicate stability and a superior adaptability, which could fully satisfy the requirements of the electromotor soft starting process.
