| 摘 要： | 提出一种在线测量电机系统载荷状态下的转动惯量的方法。该方法对施加载荷的电机驱动系统进行自由减速试验，先由电机驱动器在线获取电机运行参数，再根据自由减速运动规律和负载的物理模型，求解得到系统的载荷转动惯量。对常见负载的电机驱动系统的自由减速过程进行了数学推导、软件仿真与实验验证，计算得到的转动惯量与仿真结果和实测结果相吻合，证明了该测试方法的可行性。该方法适用于载荷状态下的电机驱动系统转动惯量测量，具有操作简便、测量精确度高和适用范围广的特点。

| Abstract: | An online measurement method for the rotational inertia of the loaded motor drive system is proposed. The method is realized by the free retardation experiment on the motor drive system. The motor controller obtains real-time operation variables at first, and then works out the system inertia according to the free retardation mechanism and the physical principle of the load. The retardation mechanisms of several conventional load types are analyzed by mathematical deductions, software simulations and experimental tests. The calculated value of the system inertia is highly coincident with the one carried out by simulations and experiments, so as to prove the feasibility of the method. In summary, this method is suitable for measuring the inertia of the loaded motor drive system, due to its easy usage, high accuracy and wide field of application. |
