摘要
自抗扰控制(ADRC)是在继承经典PID不依赖于对象模型的基础上,通过改进经典PID固有缺陷而形成的新型控制技术。为满足无刷直流电机控制系统性能要求,在分析永磁无刷直流电机特点及使用现状的基础上,建立了基于自抗扰控制器的无刷直流电机控制系统。仿真结果表明,自抗扰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,算法简单、工程适用性较强,系统具有良好的动态响应性能。
The classical PID control features independent from object model, but some inherent defects. Auto-disturbance-rejection control （ ADRC ） is a new kind of control technology that inheriting the merits and overcoming the demerits of classical PID. In order to meet the performance requirement of the control system for brushless DC motors, the control system based on ADRC is established on the basis of the analysis on the characteristics and current status of application of permanent magnet brushless DC motors. The result of simulation indicates that the ADR controller offers higher adaptability and robustness to variation of external disturbance and the uncertainty of the model of the motor, and it is simple in arithmetic, more flexible in engineering and better in dynamic response.
