Summary: | The utility model discloses a rotary inertia identifier of an alternating current permanent magnetic synchronous motor servo system, which comprises a speed command generator, a speed controller, a rotation torque controller, a rotary inertia calculator, a digital low-pass filter, a storage display, a motor and a load, wherein the speed command generator, the speed controller, the rotation torque controller, the motor and the load are connected sequentially, the rotation torque controller and the speed command generator are connected with the rotary inertia calculator, the rotary inertia calculator is connected with the digital low-pass filter, and the digital low-pass filter is connected with the storage display. During a rotary inertia identification process, the rotary inertia identifier guarantees successful complement of rotary inertia identification and high identification precision on conditions that load rotation torque changes irregularly and rotary inertia varies. |
