模糊控制器在无速度传感器矢量控制变频调速系统中的应用

本文将模糊控制引入无速度传感器的电流型转差矢量控制交流传动系统中，给出了带自调整因子的模糊控制器。文中对转差矢量控制算法与速度观测器进行了研究，给出了控制系统的结构，并在此基础上进行了仿真研究。对模糊控制与ＰＩ控制作对比研究的结果表明，模糊控制器较常规ＰＩ控制器对参数变化与负载扰动不敏感，可使系统具有更强的鲁棒性。

Application of Fuzzy Controllers in the Variable-Frequency System with the Sf-Vector Control without Speed-Sensor

In this paper fuzzy control is introduced in sf-vector control system of an induction motor,which has not speed sensor,and the fuzzy controllers with self-tuning factor are given.On the basis of researches in concepts and algorithms of sf-vector control and speed observer,the structure of control system is presented, and the system is simulated.The results of simulation show that fuzzy contrllers are insensitive to the disturbance which is caused by the change of the load and motor parameters,so they can make system more robust than conventionnal PI controller.
