Abstract
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.
