摘　　要：船舶运行环境中存在多种快速变化的扰动源,导致同步电机负载突变、电流输出产生误差等问题,从而影响电机的调速性能。因此,提出多源快变干扰船舶永磁同步电机调速控制方法。基于电机数学模型,利用分数阶积分滑模调速控制器控制电流输出;构建多源快变扰动观测器,获取多源快变总扰动,并输入至调速控制器内,实现永磁同步电机调速控制。实验结果说明,该方法控制下电流输出控制平滑,在应对多源快变干扰时能够有效减少转速跌落幅度。There are many kinds of rapidly changing disturbance sources in ship operating environment,which lead to load sudden change and current output error of synchronous motor,thus affecting the speed regulation performance of motor.Therefore,a speed control method of multi-source fast variable interference Marine permanent magnet synchronous motor is proposed.Based on the mathematical model of motor,the current output is controlled by fractional order integral sliding mode speed controller.The multi-source fast variable disturbance observer is constructed to obtain the multi-source fast vari-able total disturbance and input it into the speed control controller to realize the speed control of permanent magnet syn-chronous motor.The experimental results show that the current output control is smooth under the control of this method,which can effectively reduce the speed drop amplitude when dealing with multi-source fast variable interference.
