| 摘 要： | 自抗扰控制（ADRC）是在继承经典PID不依赖于对象模型优点的基础上，通过改进经典PID固有缺陷而形成的新型控制技术，性能优良。但对于对象变化范围大的系统，仍难获得理想的控制效果。为此，将神经网络与自抗扰控制器相结合，在分析永磁无刷直流电机特点及使用现状的基础上，建立了基于神经网络自抗扰控制器的无刷直流电机控制系统。仿真结果表明，该控制器对无刷直流电机模型的不确定性和外部扰动变化具有较强的适应性和鲁棒性。系统具有良好的动态响应性能。

| Abstract: | Inheriting the merit of independent of system model and overcoming the shortcomings of classic PID controller,auto-disturbances-rejection controller(ADRC)possesses good performance with relatively simple algorithm Through combining neural networks with auto ADRC based on the mathematical model of the brushless DC motor,a new strategy for brushless DC motor control system has been proposed in this paper.The simulation results have shown that the controllers achieve very good robustness undermodeling uncertai... |
