Title:
LOAD INERTIA IDENTIFICATION METHOD AND APPARATUS, ELECTRONIC DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/029903
Kind Code:
A1
Abstract:
Disclosed herein are a load inertia identification method and apparatus, an electronic device, and a system. The load inertia identification method comprises: acquiring an input control instruction, the motor rotating speed, and the load rotating speed of a mechanical transmission system to be tested in a previous state; according to the input control instruction, the motor rotating speed, the load rotating speed, and a state prediction equation of the mechanical transmission system, predicting a current predicted system state of the mechanical transmission system; acquiring a current measured motor rotating speed value and a current measured load rotating speed value of the mechanical transmission system; according to the current predicted system state, the current measured motor rotating speed value, and the current measured load rotating speed value, determining the current optimal estimated state of the mechanical transmission system; and according to the current optimal estimated state, determining load inertia information of the mechanical transmission system in the current state.
