为了降低载人电动飞机在巡航过程中永磁同步电机（PMSM）转速响应系统易受参数摄动和外界扰流影响，提出了一种电动飞机PMSM的转动惯量在线辨识与转矩扰动补偿滑模控制（SMC）方法。通过一种自适应遗忘因子最小二乘算法对转动惯量进行在线辨识，对控制器的参数进行实时匹配，并将辨识后的转动惯量引入龙贝格扰动观测器对负载转矩变化进行观测，同时针对扰动进行估算与补偿。以一种新型趋近率的滑模转速控制策略代替PI转速控制策略，该方法在保留SMC鲁棒性强的优点削减了滑模变结构带来的抖振干扰，提升了系统的响应速度，最终通过仿真及半实物试验方式验证了该方法的有效性。

During the cruise, the speed response system of permanent magnet synchronous motor (PMSM) in the manned electric aircraft is easily affected by parameter perturbation and external turbulence. In order to solve this problem, an online identification and torque compensation sliding mode control (SMC) method for PMSM of manned electric aircraft is put forward. The rotational inertia is identified online by the adaptive forgetting factor recursive least squares, so as to match the parameters of the controller in real time. Then, the rotational inertia is introduced into the Luenberger disturbance observer to observe the change of load torque, while estimating and compensating for the disturbance. The PI speed control method is replaced by a novel sliding speed control method. The proposed method can suppress the chattering caused by sliding variable structure and improve the response speed of the system while retaining the advantages of strong robustness of the SMC. Finally, the effectiveness of the method is verified by the simulation experiments and the semi-physical tests.
