摘　　要：提出一种基于模糊神经网络的模型参考自适应电机转速辨识方法,将其与SVPWM调制技术控制的变频器系统结合起来,组成了一种基于DSP的感应电机无速度传感器矢量控制系统。具体介绍了其结构及软硬件的设计。实验及仿真结果表明,该系统动态性能好,能准确跟踪电机转速的变化。This paper presents a new method of induction motor speed estimation, which is the combination of Fuzzy Neural Network(FNN) and Model Reference Adaptive System(MRAS).We combine this method with the inverter controlled by Space Vector Pulse Width Modulation (SVPWM) to form a field oriented control system of speed sensorless based on DSP.Its structure software and hardware are analyzed.The Experimental and Simulative results show that the control system has better dynamic performance and can accurately track the variation of the motor speed.
