交流变频调速系统中的自适应模糊控制研究

Application Research of Self-adaptive Fuzzy Control in the Variable Frequency Speed Regulating System of Induction Motor

针对交流电动机矢量控制系统因电机参数变化和负载波动等因素性能变差的问题,设 计了一种二维自适应模糊控制器作为交流电动机矢量控制系统的速度调节器,并由电压空间矢量 脉宽调制(SVPWM)逆变器作为电动机的供电电源来实现变频调速。仿真实验表明,系统不仅动态 和稳态性能都得到提高,而且具有良好的鲁棒性。

Due to the variation of motor parameters and load of the induction motor vector control system, the two-dimension self-adaptive fuzzy controller is designed to use at the speed adjustment of the induction motor vector control system ,also the inverter based on SVPWM is used to the speed adjustment by frequency conversion of the motor's power supply. Simulation results prove that the system can improve the static and dynamic property and is very robust.
