摘　　要：由于经典PID控制器自身所固有的缺陷,在异步电机直接转矩控制(DTC)调速中不能满足大范围高精度的调速要求。采用自抗扰控制器(ADRC)作为速度调节器,并借助对角递归神经网络(DRNN)进行参数整定,构成了新的异步电机直接转矩控制调速系统。仿真结果表明:对于异步电机直接转矩控制系统,基于对角递归神经网络整定的自抗扰控制器对电机不同参考转速的运行具有很强的适应性,在大范围调速方面比经典PID控制器性能更优越。Classic PID controller can＇t fulfill speed modulation in large-scale and high precision of speed modulation of induction motor based on direct torque control （DTC） owning to its own defects. A new direct torque control speed modulation of induction motor based on active disturbance rejection control（ADRC） with diagonal recurrent neural networks （DRNN） optimization was constituted. The simulation results show that active disturbance rejection controller based on with diagonal recurrent neural networks optimization has highly preferable applicability when motor move in different speed, dynamic performance is obvious excellent than classic PID controller in large-scale and high precision.
