摘要

由电机拖动的液压系统具有可靠性好、调速方便、效率高等优点,而三相永磁同步电机拖动的液压系统较异步电机拖动的液压系统在效率及调速精度方面更优越,在建立由三相永磁同步电机拖动的液压系统数学模型的基础上,考虑了液压系统中常见的油液黏温黏压特性、有效体积弹性模量和非线性摩擦力等3种非线性因素,使用Matlab/Simulnk软件分析了系统参量变化时系统的性能改变情况。通过仿真实验,验证了模型的正确性和有效性,为开展永磁同步电机拖动的液压系统性能研究提供了参考。
        The hydraulic system driven by the motor has the advantages of good reliability, convenient speed regulation and high efficiency, while the hydraulic system driven by the three-phase permanent magnet synchronous motor is superior to the hydraulic system driven by the asynchronous motor in efficiency and speed control accuracy. Based on the mathematical model of the hydraulic system of three-phase permanent magnet synchronous motor, the characteristics of oil viscosity, the effective volume modulus and the nonlinear frictional force of three nonlinear factors in hydraulic system were considered, and the performance changes of the system were analyzed with Matlab/simulink software. The correctness and validity of the model are verified by simulation experiment, which provides a reference for the study of the performance of the hydraulic system of the permanent magnet synchronous motor.
