| 摘 要： | 为满足潜艇侧推系统快速启动性和高可靠性要求,解决机械传感器的海水密封问题,研究了扩展卡尔曼滤波器无位置传感器永磁同步电动机控制系统,建立了标幺制下的EKF位置和转速估算模型,使应用扩展卡尔曼滤波器估算电机位置和转速时,矩阵的参数不依赖于电机参数,具有更广范围的适用性,降低了使用难度.针对电机初始位置误差造成EKF估算失败的问题提出了一种修正方法,仿真和实验证明了该方法的有效性.

| Abstract: | Extended Kalman filter(EKF) position sensorless control system of permanent magnet synchronous motor used in lateral thruster system was studied to guarantee the rapid start-up,high reliability and solve waterproof problem of mechanic sensors.A novel EKF model in per-unit system was developed to make the matrix parameters in EKF position equations and speed estimation system independent of the parameters of the motor,therefore the model can be used in wider range and reduce the difficulties.In addition,the start-up performance of EKF arithmetic was studied.A correction method for the failure of estimation in EKF caused by initial position error was presented.The simulation results as well as experimental ones illustrate the validity and efficiency of the proposed method. |
