摘要提出了一种无需参数整定的自抗扰控制器（NMT-ADRC）。ADRC具有不依赖被控对象模型、无超调、鲁棒性强的优点, 越来越受到学术界和工业界的重视。然而, ADRC的非线性反馈控制器（NLSEF）采用近似最速反馈控制（fhan）函数时需要整定三个参数, 但这三个参数没有明确的物理意义, 只能采取试凑法, 整定效果依赖于操作者的经验。针对这一问题, 依据fhan函数的特点分析了ADRC的NLSEF控制机理, 提出了NMT-ADRC控制器。在这种结构下, NLSEF不包含需要调整的参数, 故无需参数整定就可以从理论上达到良好的控制效果。为验证提出算法的有效性, NMT-ADRC被应用到PMSM控制系统中。仿真和实验结果表明, NMT-ADRC控制器可以有效控制PMSM的转速和转矩。

Abstract：A modified active disturbance rejection controller(ADRC) is proposed in this paper. ADRC attracts much attention from industry and academia for its independent on models, non-windup and robustness. However, the nonlinear state feedback(NLSEF) in ADRC adopts discrete time-optimal control synthesis(fhan) function which includes three parameters to be tuned. Since the three parameters have no physical meaning, the tuning has to use trial and error method and depends on experience of operator. To solve the problem, the control mechanism of NLSEF in ADRC is analyzed based on the characteristics of fhan function, and then a no manual tuned ADRC(NMT-ADRC) structure is proposed. NLSEF does not include any parameters which need turning in this structure. To verify the effectiveness, NMT-ADRC is applied to control permanent magnet synchronous motor(PMSM) speed and torque. Experimental results show that both the speed and torque can obtain satisfied static and dynamic performance.

Key words： Active disturbance rejection control discrete time-optimal control synthesis function permanent magnet synchronous motor parameters tuning
