摘要
针对水下航行器实航时海况复杂,恶劣的环境会对推进系统造成不利影响,降低系统中机械式位置传感器的精度甚至损坏等问题,研究了一种基于无位置传感器的复合式检测方法,在速度转换模块作用下,由高频脉振电压信号注入法平稳转换为模型参考自适应法(MRAS),并将复合式方法与单一的控制方法作比较。仿真结果表明:该复合式无位置传感器控制方法能实现推进系统永磁同步电机(PMSM)的低、中、高全速运行,提高了系统的稳定性和可靠性。
The sea condition of underwater vehicle was complex in actual navigation,and its bad environment could cause adverse effects on the propulsion system,reduce the accuracy of the position sensor in the system,and even damage it.In order to solve this problem,a sensorless detection method was studied,which used high-frequency pulse voltage signal injection method and model reference adaptive compound control method.By designing a speed switcher,the smooth switching between the two methods was realized.The simulation results show that the hybrid control method can realize the low,medium and high speed full speed operation of PMSM,and improve the stability and reliability of the system.
