摘要：

To achieve accurate control, it needs to modify motor parameters of the sensorless control of the permanent magnet synchronous propulsion motor of ship. In this paper, the model reference adaptive method (MRAS) is used for the online identification of the parameters of the permanent magnet synchronous motor. The RungeKutta method was used to establish a full-rank adjustable model, and the adaptive law was derived according to Popov's super-stability theorem. The identification of resistance and inductance parameters was completed by step identification, the identified parameters were obtained by high-frequency harmonic filtering through a low-pass filter to obtain precise motor parameters, and the actual parameters of the filtered motor were used for algorithm feedback to dynamically update the motor model. Both the software simulation and the physical platform verified that the MRAS parameter online identification algorithm can accurately and effectively identify the actual stator resistance and inductance of the motor. The sensorless control scheme for marine permanent magnet propulsion motors with parameter identification is feasible and effective. © 2020, Harbin University of Science and Technology Publication.
