永磁同步电机在舰船推进系统中的滑模控制研究

Sliding mode control of permanent magnet synchronous motor in ship propulsion system

永磁同步电机(PMSM)具有结构紧凑、功率因数高和便于维修等优点,在舰船推进系统、数控机床控制和雷达系统等工业领域有广泛的应用。永磁同步电机是一个非线性系统,受众多不确定性因素的影响,因此对其进行精确控制具有一定的难度。本文主要研究舰船推进系统的永磁同步电机,采用滑模控制策略对舰船的永磁同步电机伺服系统进行控制。

Permanent magnet synchronous motor(PMSM) has many advantages, such as compact structure, high power factor and easy maintenance. It has been widely used in many fields, such as propulsion system, control system and radar system. Permanent magnet synchronous motor(PMSM) is a nonlinear system with many uncertain factors. In this paper, the permanent magnet synchronous motor of ship propulsion system is studied, and the sliding mode control strategy is used to control the permanent magnet synchronous motor servo system.
