【Abstract】 According to the traditional control algorithm of ship power propulsion device, there is a large positioning error of the output power resistance of the power device, which leads to the lack of nonlinear ESO parameter conditional variables at the output level of the control algorithm, which results in the decrease of the overall control output accuracy of the algorithm. Aiming at the problems caused by the location of dynamic resistance and the lack of nonlinear ESO data, the stability control of ship power propulsion device is proposed. Through matching the dynamic resistance index of ship propulsion device, the distribution position of dynamic resistance is accurately located; it adopts nonlinear ESO data model to model the dynamic resistance value; according to the nonlinear ESO model data, The calculation of the stable control quantity of the power device is completed. The simulation results show that the proposed control algorithm is effective.更多还原
