摘要
异步电机调速系统中,传统PI调节器不能满足大范围高精度调速的要求。自抗扰控制器(ADRC)具有对控制对象参数变化不敏感的特性,现采用ADRC作为调节器构成了新型闭环调速系统。仿真结果表明:对于异步电机直接转矩控制系统,基于ADRC的速度调节器对电机不同转速的运行具有较强的适应性,动态性能指标明显优于传统PID控制。
Traditional PI controller can＇t fulfill speed modulation in large-scale and high precision in speed modulation of induction motor. Active disturbance rejection controller （ADRC） isn＇t sensitivity when the parameter of control object change, ADRC controller as a modulation a new closed loop speed system was constituted. The simulation results show that the speed controller based on ADRC has preferable applicability when motor move in different speed, dynamic performance is obvious excellent than traditional PID control in direct torque control of induction motor.
