Description

technical field [0001] The invention belongs to the technical field of motor control, and in particular relates to a control parameter self-tuning device of a motor control system and a tuning method thereof. Background technique [0002] Permanent magnet synchronous motors are widely used in aerospace and marine fields due to their high power density, high efficiency, and good controllability. The permanent magnet synchronous motor system has the characteristics of multi-variable, strong coupling, and high-order nonlinearity. In the vector control of synchronous motors, different flux vectors can be selected as the oriented coordinate axes. Usually, there are rotor flux orientation, air gap magnetic There are three ways: chain orientation and stator flux linkage orientation. Generally, the vector control of rotor flux orientation is adopted. The basic principle of rotor flux orientation vector control is to divide the stator current of the motor into two components, the e...
