针对传统PLC变频调速系统存在抗干扰能力弱、自适应能力差的问题，文章提出了一种基于自抗扰控制器( ADRC)的异步电机变频调速系统。此系统的核心思想是通过扩张状态观测器对系统进行扰动和补偿。从而达到控制对象可以近似线性化和确定性化的目的。测试结果表明，和传统的PLD控制方式相比，其跟随性、鲁棒性、抗干扰性和动态性能都很好，具有很好的实用价值。

PLC frequency control system for the presence of traditional anti-jamming capability is weak and poor adaptability. An ADRC(ADRC)for induction motor speed control system is presented. The core idea of this system is to make some disturbances and compensations to the system by using its extended state observer. So as to achieve the control object,it can be approximated by linearity and certainty of purpose. Test results show that the traditional PLD control compared to its follower,robustness,interference and dynamic performance are good with good practical value.
