摘　　要：针对航空发动机燃油泵用永磁同步电机的恶劣环境下工作、高可靠性要求和变负载变转速运行的特性,提出了自抗扰控制的永磁同步电机低速域无传感器控制技术。首先分析电机转速环和电流环可能的干扰,并为双环分别设计改进的非线性自抗扰控制器。然后,采用“冻结参数法”分析了非线性ESO的频域特性,并归纳参数整定原则,实现“动态补偿线性化”,增强系统抗干扰能力。最后,仿真结果表明,该非线性ADRC系统拥有良好的动态性能,能够对外部阶跃干扰和周期干扰进行有效的估计和补偿,且能适应不同的工况,有极强的鲁棒性。Aiming at the characteristics of permanent magnet synchronous motor for Aircraft engine fuel pump working in harsh environment,high reliability requirements,variable load and speed requirements,a low-speed sensor-less control of PMSM with active disturbance rejection controller(ADRC)was proposed.Firstly,the disturbance of the motor speed loop and current loop was analyzed,and the improved nonlinear active disturbance rejection controllers(ADRC)were designed for the double loops respectively.Then,the“frozen coefficient method”was used to analyze the frequency domain characteristics of the nonlinear ESO,and the principle of parameter setting was summarized to achieve the“dynamic compensation linearization”and enhance the disturbance rejection ability of the system.Finally,the simulation results show that the nonlinear ADRC system has good dynamic performance,can effectively estimate and compensate for external step disturbance and periodic disturbance,can adapt to different working conditions and has strong robustness.
