摘要
设计了一种二维自适应模糊控制器 (F C)作为无速度传感器感应电机矢量控制系统的速度调节器。这种自适应模糊控制器可以根据速度给定和负载转矩的变化实时调节解模糊的比例因子。系统使用定转子自适应磁通观测器和转速动态估计器来估算转子磁通和转速 ,有两个 PID控制器分别控制转矩和磁通的电流分量 ,输出电压空间矢量控制电机。仿真结果表明 ,与PID控制器比较 ,F C具有更好的动态性能和稳态性能 。
A self-adaptive fuzzy controller(FC) is designed for sensorless vector control system as speed controller. The controller adjusts the factor based on the reference speed and load torque. Stator and rotor adaptive flux observer and speed dynamic estimator are used to estimate the flux and speed of the rotor and two PI controllers are supposed to control the current of torque and flux, then output the voltage space vector control the motor. The simulation results demonstrate that compare to PID controller, FC has better dynamic and steady performance and it is very robust.
