摘要
针对矿用电动轮自卸车交流电驱动调速系统中感应电机参数摄动现象严重,控制鲁棒性差的难题,研究了一种基于自抗扰控制器(ADRC)的转子磁场定向矢量控制的感应电机闭环调速系统,分析了ADRC对感应电机参数摄动和外扰等不确定项的补偿作用,实现了感应电机的转子磁链和电磁转矩的动态解耦.仿真结果表明,调速系统在大范围转子电阻摄动和转矩干扰下,系统的动态性能明显优于传统PI调节器,对感应电机的其它参数变化也具有较强的鲁棒性,容易推广交流传动的其它应用中.
According to the poor robust control and large scale parameter perturbation in electric wheel dump truck speed regulation system, a kind of controller based on active disturbances rejection controller （ARDC） is researched in rotor flux oriented vector control speed regulation system, analyzing the compensation of ARDC to perturbation of parameters and external disturbance, and dynamic decoupling of rotor flux and torque is achieved. The simulation results show that the controller produces better dynamic performance such as small overshoot and speed sinking than conventional PI controller in rotor field orientation control system with large scale perturbation of rotor resistance and torque disturbance, and produces strong robust for other parameters of induction motor; therefore, it extends easily to other control systems.
