摘　　要：电推进系统采用永磁同步电机(permanent magnet synchronous motor,PMSM)直接驱动螺旋桨为飞机提供所需的动力,由于运行工况的复杂性和强耦合性,其对动态响应和扰动抑制能力提出更高的要求。为了提高系统性能,提出一种线性/非线性自抗扰混合控制方法。在线性扩张状态观测器(linear expanding state observer,LESO)和非线性扩张状态观测器(nonlinear expanding state observer,NESO)参数整定的基础上,设计带权重系数的混合控制策略。该方法有效整合LESO和NESO的优点,通过带桨测试结果验证所提方法的可行性,为工程实践奠定理论基础。The electric propulsion system is powered by permanent magnet synchronous motor(PMSM)to drive the propeller.The complexity and strong coupling of operating conditions increase requirements for dynamic response and disturbance suppression.To improve the system performance,a linear/nonlinear active disturbance rejection hybrid control method is proposed in this paper.The hybrid control strategy with weighting coefficients is designed based on the parameter tuning of linear expanding state observer(LESO)and nonlinear expanding state observer(NESO).This method effectively integrates the advantages of LESO and NESO.The feasibility of this method is verified by the test results with the propeller,which lays a theoretical foundation for engineering practice.
