Abstract

The invention discloses a method for identifying parameters of a dual-motor drive belt conveyer energy consumption model. The method includes the following steps: S10, establishing a coal mine dual-motor drive belt conveyer energy consumption model according to an energy consumption model based on a single-motor dynamic model; S20, performing parameter identification on rotating speed of the motorand load torque according to motor operation parameters of the motor after a load is applied; and S30, identifying energy consumption parameters of the dual motor drive belt conveyer according to theidentified rotating speed and load torque parameter values. The rotating speed of the motor and the load torque are identified first, the identified rotating speed value and load torque value are substituted into the energy consumption model, the problem of identification precision reduction caused by a measuring error brought by adoption of a rotating speed sensor and a torquemeter is avoided, and an identification result is closer to the reality and more accurate.

Description

technical field [0001] The invention relates to a motor parameter identification and processing method, which belongs to the technical field of motors, in particular to a parameter identification method of an energy consumption model of a belt conveyor driven by a double motor. Background technique [0002] Accurate belt conveyor energy consumption model is the key to energy consumption parameter identification and motor optimal control. The existing energy consumption model of belt conveyor is only applicable to belt conveyor driven by a single motor. [0003] Considering that when the least square method is used to identify the energy consumption parameters of the belt conveyor, the identification accuracy is greatly affected by the motor speed and load torque, so ensuring the accuracy of the motor speed and load torque parameter measurement is the key. When detecting the actual running state of the belt conveyor, the motor speed and load torque can be measured by the spee...
