摘要：针对典型自抗扰控制器(ADRC)参数较多，意义不明确，难以整定的问题，研究了一种改进的自抗扰控制器。该控制器去除了微分跟踪器(TD)模块，并采用直接误差替代扩张状态观测器(ESO)和非线性状态误差反馈控制律(NLSEF)模块中的非线性函数。将其应用于永磁同步电机转速控制，仿真结果表明，本文设计的自抗扰控制器性能优于常规的PI控制器，与典型的自抗扰控制器相比较，具有结构更简单，可调参数少等优点。

Abstract: Due to there are a lot of parameters of typical Active Disturbance Rejection Controller (ADRC) while their meanings are not clear and they are difficult to set, this article researched on a developed ADRC. The Tracking Differentiator (TD) module was omitted, while used direct error instead of nonlinear function in both Extended State Observer (ESO) and Nonlinear State Error Feedback (NLSEF). The ADRC was applied to the permanent magnet synchronous motor (PMSM) speed control system. The simulation results that, the ability of the ADRC in this article is better than the conventional PI controller, which has a more simple structure and less adjustable parameters comparing with the typical ADRC controller .
Key words: active disturbance rejection control; permanent magnet synchronous motor; vector control; parameter adjustment
